Resting heart rate is a risk factor for cardiovascular and noncardiovascular mortality: the Chicago Heart Association Detection Project in Industry

In a prospective cohort study, associations of resting heart rate with risk of coronary, cardiovascular disease, cancer, and all-cause mortality in age-specific cohorts of black and white men and women were examined over 22 years of follow-up. Participants were employees from 84 companies and organizations in the Chicago, Illinois, area who volunteered for a screening examination. Participants included 9,706 men aged 18-39 years, 7,760 men aged 40-59 years, 1,321 men aged 60-74 years, 6,928 women aged 18-39 years, 6,915 women aged 40-59 years, and 1,151 women aged 60-74 years at the baseline examination in 1967-1973. Vital status was ascertained through 1992. For fatal coronary disease, multivariate-adjusted relative risks associated with a 12 beats per minute higher heart rate (one standard deviation) were as follows: for men aged 18-39 years, relative risk (RR) = 1.27 (95% confidence interval (CI) 1.08-1.48); for men aged 40-59 years, RR = 1.13 (95% CI 1.05-1.21); for men aged 60-74 years, RR = 1.00 (95% CI 0.89-1.12); for women aged 40-59 years, RR = 1.21 (95% CI 1.07-1.36); and for women aged 60-74 years, RR = 1.16 (95% CI 0.99-1.37). Corresponding risks for all fatal cardiovascular diseases were similar to those for coronary death alone. Deaths from cancer were significantly associated with heart rate in men and women aged 40-59 years. All-cause mortality was associated with higher heart rate in men aged 18-39 years (RR = 1.11, 95% CI 1.01-1.20), men aged 40-59 years (RR = 1.16, 95% CI 1.11-1.21), and women aged 40-59 years (RR = 1.20, 95% CI 1.13-1.27). Heart rate was not associated with mortality in women aged 18-39 years. In summary, heart rate was a risk factor for mortality from coronary disease, all cardiovascular diseases, and all causes in younger men and in middle-aged men and women, and for cancer mortality in middle-aged men and women.     

Body mass index and cardiovascular mortality at different levels of blood pressure: a prospective study of Norwegian men and women.

STUDY OBJECTIVE--The study investigated the joint effect of body mass index and systolic blood pressure on cardiovascular and total mortality. DESIGN--This was a prospective cohort study. The main outcome measures were age adjusted mortality and relative risks estimated from survival models. SETTING--The population of the city of Bergen, Norway. PARTICIPANTS--Subjects were 21,145 men and 30,330 women aged 30-79 years at the time of examination in 1963. MAIN RESULTS--Both cause specific and all cause mortality increased with systolic blood pressure within each category of body mass index. Stroke mortality was not significantly associated with body mass index when adjusted for systolic blood pressure in either age group of men or women. Coronary heart disease mortality increased on average 30% per 5 kg/m2 increase in body mass index in men and women aged 30-59 years at baseline. Adjusted for systolic blood pressure, the relative risks were reduced to 1.20 (95% confidence interval (CI) 1.12, 1.29) in men and 1.10 (95% CI 1.03, 1.18) in women. They were similar at each level of systolic blood pressure. For coronary heart disease mortality in men and women aged 60-79 years at measurement a negative interaction between body mass index and systolic blood pressure was suggested in the first five years. Excluding the first five years, adjusted relative risks per 5 kg/m2, were 1.05 (95% CI 0.96, 1.15) in men and 1.11 (95% CI 1.04, 1.17) in women in the older age group. There was an upturn in cardiovascular mortality at low levels of body mass index in both age groups of women, but not in men. CONCLUSIONS--Hypertension is an important risk factor for cardiovascular and all cause mortality even in the obese. Body mass index is generally a weak predictor of cardiovascular mortality in this population. It is a stronger risk factor of coronary death in men when measured at a younger age. Thin people with hypertension are not at particularly high risk of death from coronary heart disease compared with their obese counterparts, except possibly in the first few years after measurement in the elderly. Being underweight is associated with increased risk of death from all cardiovascular causes in women, but not in men.     

Managing heart failure in primary care: first steps in implementing the National Service Framework

BACKGROUND: Heart failure is common, causes considerable morbidity, and imposes a major financial burden on both society and the National Health Service. The National Service Framework (NSF) for Coronary Heart Disease (CHD) set national standards for the management of people with heart failure in England. We examined how patients with heart failure were investigated and treated compared with NSF standards, and explored the current constraints in improving the care of these patients. METHODS: This study was carried out in two general practices (total list size 19,600) in south London. Using a computer search strategy, patients with possible heart failure were identified and clinical data extracted from their medical records. Workshops on heart failure were held at a national conference on disease management in primary care, and key stakeholders were interviewed to identify constraints in improving management. RESULTS: Ninety patients with heart failure were identified through the computerized search. Seventy-eight patients (87 per cent) had a Read code for heart failure on their electronic medical record. Forty-eight (53 per cent) patients were men and 10 (12 per cent) were aged less than 65 years. Forty-nine per cent of patients had undergone an electrocardiogram and 42 per cent an echocardiogram. Angiotensin-converting enzyme (ACE) inhibitors were prescribed to 54 per cent of patients. In the workshops and stakeholder interviews, healthcare professionals and managers reported difficulties in implementing the NSF. They expressed concerns regarding the difficulties in confirming a diagnosis of heart failure, including access to echocardiograms, prescribing ACE inhibitors among older patients, and the additional workload and resources needed to ensure they met the NSF standards for heart failure. CONCLUSION: The accurate identification of heart failure patients and recording of clinical information as part of disease registers needs to improve if primary care teams are to meet the NSF standards. There is also scope to improve the investigation and treatment of heart failure patients in primary care. Achieving these objectives will require additional resources.     

Cardiovascular risk factors and prevalence of coronary heart disease in type 2 (non-insulin-dependent) diabetes

The relationship between cardiovascular risk factors and the prevalence of coronary heart disease was examined in 152 Type 2 diabetic patients (65 men, 87 women) aged 35–54 years and in 105 randomly selected control subjects (46 men, 59 women). Coronary heart disease, defined by symptoms and ECG abnormalities, was 1.2 times higher in male and 3.4 times higher in female diabetic patients than in the controls. In logistic regression analysis (including diabetes, age, body mass index, triglycerides, HDL-cholesterol, non-HDL-cholesterol and hypertension) diabetes showed an independent, significant association to coronary heart disease in women, whereas hypertension was independently related to coronary heart disease in men.Corresponding author.     

Cardiovascular risk factors in Mexican American adults: a transcultural analysis of NHANES III, 1988-1994

OBJECTIVES: This study examined the extent to which cardiovascular disease risk factors differ among subgroups of Mexican Americans living in the United States. METHODS: Using data from a national sample (1988-1994) of 1387 Mexican American women and 1404 Mexican American men, aged 25 to 64 years, we examined an estimate of coronary heart disease mortality risk and 5 primary cardiovascular disease risk factors: systolic blood pressure, body mass index, cigarette smoking, non-high-density lipoprotein cholesterol, and type 2 diabetes mellitus. Differences in risk were evaluated by country of birth and primary language spoken. RESULTS: Estimated 10-year coronary heart disease mortality risk per 1000 persons, adjusted for age and education, was highest for US-born Spanish-speaking men and women (27.5 and 11.4, respectively), intermediate for US-born English-speaking men and women (22.5 and 7.0), and lowest for Mexican-born men and women (20.0 and 6.6). A similar pattern of higher risk among US-born Spanish-speaking men and women was demonstrated for each of the 5 cardiovascular disease risk factors. CONCLUSIONS: These findings illustrate the heterogeneity of the Mexican American population and identify a new group at substantial risk for cardiovascular disease and in need of effective heart disease prevention programs.     

Management of cardiovascular risk factors in people with diabetes in primary care: cross-sectional study

OBJECTIVES: Cardiovascular disease is the major cause of morbidity and mortality in people with diabetes. The management of cardiovascular risk factors in people with diabetes in primary care was compared with National Institute of Clinical Excellence guidelines. DESIGN: A cross-sectional study in 26 general practices, with a combined list size of 256,188 patients, participating in the Kent, Surrey and Sussex Primary Care Research Network. Primary outcomes were process of care measures. METHODS: Analysis of general practice computer data on the management of 5980 patients with diabetes, of whom 86% were aged 45 years and over. RESULTS: The prevalence of diabetes was 2.0% in women and 2.6% in men, much lower than the estimated expected prevalence of 4.8% for women and 3.3% in men. Blood pressure was well recorded (96% in both sexes), cholesterol levels less well (79% of women, 84% of men). Hypertension (78% of women, 72% of men) was common. Twenty-one percent of women and 16% of men had a blood pressure above 160/100 mmHg, suggesting under use of antihypertensive therapy. Cholesterol levels were >or=5 mmol/l in 46% of women and 38% of men. Lipid-lowering drugs were prescribed in 38% of women and men. Aspirin was prescribed in 38% of women and 40% of men. CONCLUSIONS: There is an under-diagnosis of diabetes and an under-treatment of blood pressure and blood cholesterol, more marked in women than in men. There is scope for improved management within general practice, including addressing sex inequalities.     

Distribution of echocardiographic parameters and their associations with cardiovascular risk factors in the Rotterdam Study

Insight into echocardiographic parameters in the general population may facilitate early recognition of ventricular dysfunction, reducing the population morbidity and mortality of heart failure. We examined the distribution of structural, systolic and diastolic echocardiographic parameters and their associations with cardiovascular risk factors in the Rotterdam Study, a population-based cohort study in men and women aged ≥55 years. Participants with prevalent heart failure, myocardial infarction and atrial fibrillation and flutter were excluded. Echocardiographic parameters were assessed using two-dimensional, M-mode and Doppler echocardiography. Echocardiograms were available in 4,425 participants. Structural parameters were generally larger in men, and most consistently associated with age, body mass index and blood pressure in both sexes. Prevalence of moderate or poor left ventricular systolic function was 3.9% in men and 2.1% in women. Age, body mass index and blood pressure were most consistently associated with systolic function. E/A ratio was lower in women than in men. Age and diastolic blood pressure were most consistently associated with E/A ratio in both sexes. In conclusion, ventricular systolic and diastolic dysfunction is present in asymptomatic individuals. Selected established cardiovascular risk factors are associated with structural, systolic and diastolic parameters.     

Reversal of heart failure remodeling in women

Epidemiological studies suggest that women with heart failure differ from men with heart failure in that their survival is better. Therapeutic trials have not clearly demonstrated a survival benefit for women. This study was to determine the tolerance for high doses of angiotensin-converting enzyme (ACE) inhibitor-nitrates in women versus men and to compare their symptomatic response, exercise tolerance, and ventricular functional improvement over 1 year. Eighty-eight sequential patients with heart failure, 54 men and 34 women with left ventricular ejection fraction < or = 35%, were prospectively followed for 1 year. For all patients, ACE inhibitor-nitrate therapy was intensified. Each patient had three 6-monthly echocardiograms at baseline, at 6 months, and at 1 year, and metabolic stress testing. Patients were 57.3 +/- 12.3 years old, with New York Heart Association (NYHA) class severity 2.6 +/- 1.0. Lisinopril dosages were raised from 14 +/- 14 mg/day to 57 +/- 26 mg/day, isosorbide mononitrate from 15 +/- 27 mg/day to 126 +/- 72 mg/day, and carvedilol (n = 34) to 17 +/- 16 mg/day. Women and men were epidemiologically comparable, with similar baseline echocardiographic parameters (left ventricular ejection fraction 19% +/- 7% versus 17% +/- 6%, respectively). Both tolerated up-titration in medical therapy. Final 12-month ejection fractions were equivalent for women and men at 34% +/- 17% and 34% +/- 13%, respectively, with similar improvements in left ventricular diameters. At 1 year, women had higher resting heart rates and remained more symptomatic with lower exercise capacity. However, the relative changes in NYHA status and aerobic capacity were similar for women and men. Thus, both women and men tolerated uptitrated ACE inhibitor-nitrate medical therapy, with comparable reversal of heart failure remodeling. Although women continued to be more symptomatic than men, relative improvements in symptomatic status, in exercise capacity, and in hospitalization rate were equivalent.     

Mortality from coronary heart disease and stroke for six ethnic groups in California, 1985 to 1990

Coronary heart disease and stroke death rates were compared for six ethnic groups (non-Hispanic white, Hispanic, African-American, Chinese, Japanese, and Asian Indian) by sex and age (25 to 44, 45 to 64, 65 to 84, and 25 to 84 years old) using California census and 1985 to 1990 death data. African-American men and women in all age groups had the highest rates of death from coronary heart disease, stroke, and all causes (except for coronary heart disease in the oldest men). Hispanics, Chinese, and Japanese in all age-sex groups had comparatively low death rates for coronary heart disease and stroke, although stroke was proportionally an important cause of death for Chinese and Japanese groups. Coronary heart disease was an important cause of death for Asian Indians although death rates were generally not higher than those for other ethnic groups. Ethnic differences were most marked for women and younger age groups.     

Ambulance Transport of the Oldest Old in Tokyo: A Population-Based Study

Background

Few studies have investigated ambulance utilization in people aged 85 years or older, ie, the oldest old.

Methods

We conducted a 1-year population-based observational study of patients transported by ambulance to emergency departments in Tokyo, Japan, which has a population of about 12 million. Demographic data, symptoms/events associated with ambulance transport, and the proportion of hospital admissions were recorded. Transport rates by age and sex were calculated using data for the background population and ambulance transports, and the 10 most frequent symptoms/events requiring transport were compared between the oldest old and those aged 65 to 84 years.

Results

Of the 642 764 patients who were transported to hospitals by ambulances, 59 570 (9%) were aged ≥85 years; 64% were women. The annual ambulance transport rate for this population was 250 per 1000/year and was significantly greater than the rate (90 per 1000/year) for those aged 65 to 84 years. The highest rate was for men aged 85 to 99 years (292 per 1000/year). Among the oldest old, the most frequent reason for ambulance transport was fall (38.5 per 1000/year), and the symptom most likely to result in hospital admission was dyspnea.

Conclusions

The ambulance transport rate for the oldest old was high, particularly among men aged ≥95 years. To reduce the need for ambulance transport among the oldest old, preventive care is needed to reduce falls and acute exacerbations of cardiac and respiratory disorders.Key words: ambulance services, oldest old, symptom, admission, population-based study     

Prevalence and management of coronary heart disease in primary care: population-based cross-sectional study using a disease register

BACKGROUND: Patients with coronary heart disease are at high risk of further coronary events. Hence, one of the main priorities in the National Service Framework for Coronary Heart Disease strategy is the identification and treatment of patients with pre-existing coronary heart disease. We aimed to determine the prevalence of established coronary heart disease in a large primary care population and to compare the management of risk factors in these patients with the standards given in the National Service Framework. METHODS: A population-based cross-sectional study was carried out using data collected from primary care. Sixty-three general practices (total list size 378,021) in four primary care groups in SW London took part. Data collection was confined to 103,613 patients over 44 years of age. We calculated age- and sex-specific and age-standardized prevalence rates, and age-adjusted relative risks for men and women. RESULTS: A total of 6,778 patients with coronary heart disease were identified (8 per cent of men and 5 per cent of women over 44 years of age). There was a history of myocardial infarction in 30 per cent (1204/3991) of men and 22 per cent (613/2787) of women (relative risk 1.57; 1.37-1.81). Coronary revascularization procedures had been performed in 27 per cent (1068/3991) of men and 11 per cent (312/2787) of women (2.02; 1.73-2.35). Most patients had been assessed for hypertension (89 per cent (3538/3991) of men; 90 per cent (2500/ 2787) of women), but in many patients blood pressure was poorly controlled (26 per cent (902/3538) of men; 27 per cent (678/2500) of women). Total cholesterol had been recently measured in 51 per cent (2018/3991) of men and 44 per cent (1218/2787) of women and was elevated in 44 per cent (881/ 2018) of men and 59 per cent (716/1218) of women (0.74; 0.69-0.79). Statins were prescribed to 49 per cent (1967/3991) of men and 38 per cent (1064/2787) of women (1.06; 1.00-1.12). Aspirin was prescribed to 65 per cent (2586/3991) of men and 59 per cent (1631/2787) of women (1.08; 1.03-1.14). Beta-blockers were prescribed to 20 per cent (181/913) of men and 15 per cent (72/499) of women with a history of myocardial infarction (1.11; 0.85-1.44). CONCLUSIONS: Most patients with coronary heart disease in primary care were being treated with aspirin but less than half with statins or beta-blockers. More men than women were treated with aspirin and statins, even though women had higher cholesterol levels than men. Men were also more likely to have a confirmed diagnosis and to have undergone a coronary revascularization procedure. There is considerable scope for improving the secondary prevention of coronary heart disease and addressing gender inequalities in primary care.     

The Framingham Disability Study: relationship of various coronary heart disease manifestations to disability in older persons living in the community.

The relation between coronary heart disease and disability was examined in 2,576 community-dwelling women and men ages 55-88 years. These Framingham Study participants were originally recruited in 1948-51 for an examination of cardiovascular disease. Twenty-seven years later, remaining members of the cohort were interviewed to ascertain physical abilities, and a score on a disability scale was assigned. Multivariate logistic analyses examined disability in relation to uncomplicated angina pectoris (AP), complicated AP, and coronary heart disease other than AP, controlling for possible confounders. In younger and older women and men, uncomplicated and complicated AP were associated with disability. Coronary heart disease other than AP was associated with disability only in the younger men. Congestive heart failure predicted disability only in the women. These results suggest that onset of AP should be recognized as a critical point in the development of disability and that AP is a better predictor of disability than is myocardial infarction or coronary insufficiency.     

Demographics of the prevalence, incidence, and management of coronary heart disease in the elderly and in women.

Cardiovascular disease constitutes an expanding problem in the elderly because of the increasing size of the aged population. Atherosclerosis, hypertension, and diabetes are responsible for the predonderance of cardiovascular disease, which causes 70% of all deaths beyond age 75. Coronary heart disease (CHD) is the most common and most lethal cardiovascular event in both sexes, exacting a large toll in disability and deteriorated quality of life in old age. Unrecognized myocardial infarctions are especially common and are as serious as symptomatic infarctions. beyond age 65, women are as vulnerable to cardiovascular death as men. The predisposing modifiable risk factors for coronary disease, stroke, peripheral arterial disease, and cardiac failure are similar in young and old and in men and women. These include hypertension, dyslipidemia, impaired glucose tolerance, physical indolence, and cigarette smoking. An attenuated risk ratio for some risk factors is offset by a greater incidence of cardiovascular events in advanced age so that the attributable risk and the potential benefit of treatment rise with age. Because the major risk factors predict CHD as efficiently in the elderly as in the young, and the decline in cardiovascular mortality has included the elderly, preventive efforts in the elderly may have substantial potential benefit. At advanced age, total cholesterol levels are considerably higher in women than in men. Some 10 million elderly, two-thirds of whom are women, may require investigation and treatment for elevated lipid levels, as determined by National Heart, Lung, and Blood Institute (NHLBI) guidelines. Because of the preponderance of women in the elderly population, trials of the efficacy of correcting risk factors in general, and lipids in particular, should include women.     

Incidence of hypertension and non-insulin dependent diabetes mellitus and associated risk factors in a rapidly developing Caribbean community: the St James survey, Trinidad.

OBJECTIVE: To compare the incidence rates of hypertension and non-insulin dependent diabetes mellitus in relation to ethnicity and other characteristics in a rapidly developing community. DESIGN: Prospective surveillance of a total community for five years. SUBJECTS: Cohort of 2491 men and women aged 35 to 69 years (79% response), of African, Indian and "other' (mainly Afro-European) descent. RESULTS: During surveillance, secular increases occurred in fasting blood glucose concentrations in both sexes and in body mass index (BMI) in men, with apparent secular reductions in systolic blood pressure in both sexes. Incidence rates of hypertension did not differ significantly with ethnicity, ranging between 33 and 41 per 1000 person-years in men and between 27 and 32 per 1000 person-years in women. In men, the incidence of diabetes (per 1000 person-years) in Indians (24) was significantly higher than in Africans (13) and others (11). In women, the diabetic incidence was similar to that for men in Indians (23) and Africans (14), but in others was twice that in men (21). In both sexes, weight gain was an important risk factor for hypertension, whereas risk of diabetes increased with BMI at baseline. The increased risk of diabetes in Indians among men was independent of baseline BMI and blood glucose. CONCLUSION: Apart from the increased risk of diabetes in Indians, ethnicity had no significant influence on incidence rates of hypertension and diabetes in Trinidad. Secular increases in blood glucose in both sexes and in BMI in men probably contributed to the concurrent increase in mortality from coronary heart disease in this community.     

Evaluating the impact of repeated community-wide health surveys on cardiovascular morbidity and mortality in the busselton population

OBJECTIVE: To evaluate the impact of repeated community-wide mass health examinations on cardiovascular mortality and hospital morbidity trends in Busselton. METHOD: Population census, hospital admission and death data were used to calculate and compare cardiovascular mortality rates from 1965 to 1998 and hospital morbidity rates from 1971 to 1998 in Busselton residents aged 40 to 84 years with the remainder of the south-west region of Western Australia. RESULTS: Among men aged 40-69 years, the calendar year trends in standardised cardiovascular mortality and morbidity ratios were relatively flat and non-significant. Among women aged 40-69 years, the mortality ratio declined significantly up to 1989 (p = 0.03) but not over the whole period (p = 0.12), and the downward trend in the morbidity ratio did not reach statistical significance (p = 0.21). Among men aged 70-84 years, both the mortality and morbidity ratios rose significantly over time, whereas among women aged 70-84 years the mortality ratios showed a flat trend and the morbidity ratios a rising trend. These increasing trends were opposite to what was expected if the surveys had a beneficial impact. CONCLUSION: This analysis of trends, while failing to demonstrate a clear benefit of repeated mass health screenings on cardiovascular event rates, also highlights the difficulties in evaluating the longer-term impact on event rates of such programs and suggests that negative conclusions should be made with caution.     

The new old epidemic of coronary heart disease

OBJECTIVES: This study quantified the consequences for prevalence of increased survival of coronary heart disease (CHD) in the Netherlands from 1980 to 1993. METHODS: A multistage life table fitted observed mortality and registration rates from the nationwide hospital register. The outcome was prevalence by age, sex, period, and disease state. RESULTS: The prevalence of CHD from 1980 to 1993 was 4.4% (men, aged 25 to 84 years) and 1.4% (women, aged 25 to 84 years). Between 1980-1983 and 1990-1993, the incidence changed little, but age-adjusted prevalence increased by 19% (men) and 59% (women). CONCLUSIONS: Sharply decreasing mortality but near-constant attack rates of CHD caused distinct increases in prevalence, particularly among the elderly.     

Impact of cardiovascular diseases on activity limitations and need for help among older persons

BACKGROUND AND OBJECTIVE: The aim of this study was to estimate the importance of specific chronic cardiovascular diseases (CVDs) as determinants of disability. METHODS: One thousand two hundred eighty-eight (86%) participants from a random population sample of 1,500 individuals (from two geographical regions of Finland) aged 65-74 years were interviewed and clinically examined in 1997. RESULTS: CVDs were strongly associated with disability. However, mental disorders were the strongest determinant of disability. Of specific CVDs, cerebrovascular diseases in men, and myocardial infarction, heart failure, and cerebrovascular diseases in women were significantly associated with disability after adjustment for age and comorbidity. In men 33% and in women 24% of disability was attributable to CVD, excluding lone hypertension. CONCLUSION: CVDs are important determinants of disability among Finns aged 65-74 years. Due to the growing number of elderly people with CVDs, disability associated with these diseases is likely to become a growing social and health burden to the community.     

The effects of changes in smoking habits on coronary heart disease mortality.

Coronary heart disease (CHD) mortality declined by about 20 per cent between 1965 and 1976. During the same period there were substantial decreases in the proportion of adults who smoked based on data from the National Health Interview Survey (HIS). This study examines the extent to which changes in smoking can account for the decrease in CHD mortality for men and women aged 35-64 years. By applying US smoking levels (estimated from HIS) to data from four epidemiologic studies on the relative risk of CHD death by amount smoked, we obtain estimates of the portion of the decline in CHD mortality attributable to changes in smoking. Smoking changes among women were not generally consistent with declines in CHD mortality. For men, the estimated impact of smoking on CHD mortality varied considerably depending upon which study was used to estimate the relative risk by amount smoked.     

Smoking cessation and mortality from cardiovascular disease among Japanese men and women: the JACC Study

To examine the effect of smoking cessation on cardiovascular disease mortality in Asians, the authors conducted a 10-year prospective cohort study of 94,683 Japanese (41,782 men and 52,901 women) aged 40-79 years who were part of the Japan Collaborative Cohort Study for Evaluation of Cancer Risk (JACC Study). During 941,043 person-years of follow-up between 1989-1990 and 1999, 698 deaths from stroke, 348 from coronary heart disease, and 1,555 from total cardiovascular disease occurred in men and 550, 199, and 1,155, respectively, in women. For men, the multivariate relative risks for current smokers compared with never smokers were 1.39 (95% confidence interval (CI): 1.13, 1.70) for stroke, 2.51 (95% CI: 1.79, 3.51) for coronary heart disease, and 1.60 (95% CI: 1.39, 1.84) for total cardiovascular disease. The respective relative risks for women were 1.65 (95% CI: 1.21, 2.25), 3.35 (95% CI: 2.23, 5.02), and 2.06 (95% CI: 1.69, 2.51), with larger excess risks for persons aged 40-64 years than for older persons. The risk decline after smoking cessation occurred for coronary heart disease and total cardiovascular disease within 2 years and for total stroke after 2-4 years. For each endpoint and in both age subgroups of 40-64 and 65-79 years, most of the benefit of cessation occurred after 10-14 years following cessation. Findings imply the importance of smoking cessation at any age to prevent cardiovascular disease in Japanese.
