Introduction
Coronary artery ectasia is an uncommon disease that has been increasingly noticed as the increase in utilization of coronary angiograms. The aim of this study is to characterize coronary artery ectasia in the population of Saudi Arabia.Methods
This is a retrospective study involved all patient with invasive coronary angiogram that was done at a tertiary hospital in Saudi Arabia from January 2011 to December 2013.Results
A total of 1115 coronary angiograms were reviewed. Coronary artery ectasia was found in 67 patients (6% of all coronary angiograms). The right coronary artery was involved in 73% of cases. And 43% of the cases had severe ectasia.Conclusion
The prevalence of coronary artery ectasia in Saudi Arabia among patient who went for coronary angiography is higher than what has been published in previous studies and a significant number of patients have severe disease. 相似文献2.
Background
Given that diabetes is an extremely common disorder in Saudi Arabia, the National Diabetes Registry was designed by King Saud University Hospital Diabetes Center in collaboration with King Faisal Specialist Hospital & Research Center, Riyadh, Saudi Arabia, in the year 2001. The aim of the registry is to identify risk factors related to diabetes and to provide statistics to public health programs and health care professionals for use in planning and evaluation. The registry was designed to provide information on the extent and nature of specific types of diabetes, diabetes complications, and treatment of diabetes in the Kingdom.The registry has been available since 2001, with major collaborations from 26 hospitals as part of Phase I in which 100,000 patient data is to be collected on a regional level from Ar-Riyadh before extending the program to other regions of Saudi Arabia.Methods
The web application was designed using relational database techniques along with on-line help topics to assist users to get acquainted with application functionalities. All Internet forms were designed with validation checks and appropriate messages to ensure quality of data.The security measures established within the application ensure that only authorized users can gain access to the functionalities of the registry at allowed times. Administrative features were designed to manage the registry-related operations easily.Results
The diabetes registry has been in operation for almost 10 years, and around 67,000 patients have been registered to date. The Web-application offers an anytime-anywhere access to the registry’s data, removing geographical boundaries and allowing the national registry to provide real-time data entry, updates, reporting, and mapping functionalities more easily.Conclusion
Merging related information in the form of databases can provide improved health care operations through instant access to data, ease of managing complex data structures, and creation of reports to be used by health care planners and hospital administrators. 相似文献3.

Objectives
The Saudi Project for Assessment of Coronary Events (SPACE) registry is the first in Saudi Arabia to study the clinical features, management, and in-hospital outcomes of acute coronary syndrome (ACS) patients.Methods
We conducted a prospective registry study in 17 hospitals in Saudi Arabia between December 2005 and December 2007. ACS patients included those with ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction and unstable angina; both were reported collectively as NSTEACS (non-ST elevation acute coronary syndrome).Results
5055 patients were enrolled with mean age ± SD of 58 ± 12.9 years; 77.4% men, 82.4% Saudi nationals; 41.5% had STEMI, and 5.1% arrived at the hospital by ambulance. History of diabetes mellitus was present in 58.1%, hypertension in 55.3%, hyperlipidemia in 41.1%, and 32.8% were current smokers; all these were more common in NSTEACS patients, except for smoking (all P < 0.0001). In-hospital medications were: aspirin (97.7%), clopidogrel (83.7%), beta-blockers (81.6%), angiotensin converting enzyme inhibitors/angiotensin receptor blockers (75.1%), and statins (93.3%). Median time from symptom onset to hospital arrival for STEMI patients was 150 min (IQR: 223), 17.5% had primary percutaneous coronary intervention (PCI), 69.1% had thrombolytic therapy, and 14.8% received it at less than 30 min of hospital arrival. In-hospital outcomes included recurrent myocardial infarction (1.5%), recurrent ischemia (12.6%), cardiogenic shock (4.3%), stroke (0.9%), major bleeding (1.3%). In-hospital mortality was 3.0%.Conclusion
ACS patients in Saudi Arabia present at a younger age, have much higher prevalence of diabetes mellitus, less access to ambulance use, delayed treatment by thrombolytic therapy, and less primary PCI compared with patients in the developed countries. This is the first national ACS registry in our country and it demonstrated knowledge-care gaps that require further improvements. 相似文献5.

Background:
Data from over 4 decades have reported a higher incidence of silent infarction among patients with diabetes mellitus (DM), but recent publications have shown conflicting results regarding the correlation between DM and presence of pain in patients with acute coronary syndromes (ACS).Objective:
Our primary objective was to analyze the association between DM and precordial pain at hospital arrival. Secondary analyses evaluated the association between hyperglycemia and precordial pain at presentation, and the subgroup of patients presenting within 6 hours of symptom onset.Methods:
We analyzed a prospectively designed registry of 3,544 patients with ACS admitted to a Coronary Care Unit of a tertiary hospital. We developed multivariable models to adjust for potential confounders.Results:
Patients with precordial pain were less likely to have DM (30.3%) than those without pain (34.0%; unadjusted p = 0.029), but this difference was not significant after multivariable adjustment, for the global population (p = 0.84), and for subset of patients that presented within 6 hours from symptom onset (p = 0.51). In contrast, precordial pain was more likely among patients with hyperglycemia (41.2% vs 37.0% without hyperglycemia, p = 0.035) in the overall population and also among those who presented within 6 hours (41.6% vs. 32.3%, p = 0.001). Adjusted models showed an independent association between hyperglycemia and pain at presentation, especially among patients who presented within 6 hours (OR = 1.41, p = 0.008).Conclusion:
In this non-selected ACS population, there was no correlation between DM and hospital presentation without precordial pain. Moreover, hyperglycemia correlated significantly with pain at presentation, especially in the population that arrived within 6 hours from symptom onset. 相似文献6.

Noncompaction cardiomyopathy (NCCM) is a primary, genetic cardiomyopathy with variable clinical manifestations that include mitral regurgitation (MR).
Methods
This study comprised patients diagnosed with NCCM and MR in two cardiac centers (King Abdul-Aziz Cardiac Center, Riyadh, Kingdom of Saudi Arabia and Sudan Heart Institute, Khartoum, Sudan), and seen in the period between 2002 and 2013. The study describes follow up, clinical, echocardiographic, and histopathological findings.Results
Nineteen cases (85% females) were identified. Ten percent of the cases had relapses and remissions of heart failure. Echocardiographic features included leaflet retraction in all patients, characteristic malcoaptation, and a zigzag deformity of anterior leaflet in 57% of patients. Ruptured chordae were found in 15% of the patients. One patient had pathological examination of the mitral valve which showed myxomatous degeneration, and sclerotic and calcific changes.Conclusion
We describe and discuss a new mechanism for MR caused by NCCM with identifiable clinical and echocardiographic features, and pathological correlations. 相似文献7.
BACKGROUND:
South Asians (SAs) have a higher prevalence of coronary artery disease than Caucasians. The long-term prognosis following acute coronary syndromes (ACS) in SA compared with non-SA patients is unclear.OBJECTIVES:
To compare the long-term adverse cardiovascular outcomes between SA and non-SA patients who have ACS.METHODS:
A case-control study of 65 consecutive SA patients admitted with ACS to the McGill University Health Centre (Montreal, Quebec) between 1995 and 2000 was conducted. Control subjects included 65 non-SA patients admitted to the same hospital with ACS matched by age, sex and year of hospitalization.RESULTS:
The mean ± SD age was 59.7±9.9 years and 12% of patients were women. There were more cases of diabetes mellitus among the SA patients than non-SA patients (43% versus 23%, respectively). Only 19% of SA patients were active smokers, compared with 34% of non-SA patients. At one year, 35% of SA patients had undergone coronary artery bypass graft surgery, compared with 22% of non-SA patients. One-year mortality was increased among the SA patients compared with the non-SA patients (6% versus 2%, respectively). However, SA ethnicity was not an independent predictor of one-year adverse cardiovascular outcomes.CONCLUSIONS:
The present study demonstrated an increased prevalence of diabetes mellitus among the SA patients with ACS compared with non-SA patients. SA patients had increased one-year mortality compared with non-SA patients. However, SA ethnicity was not an independent predictor of one-year mortality and coronary intervention. 相似文献8.
BACKGROUND:
Studies have shown that primary percutaneous coronary intervention (PCI), when performed by an experienced operator immediately after admission in a high-volume tertiary care centre, results in lower in-hospital mortality, and decreased risk of reinfarction and stroke. Furthermore, for those communities without a PCI centre, transport of patients to a PCI centre within 90 min is superior to thrombolysis. Chilliwack General Hospital (CGH, Chilliwack, British Columbia) has a unique situation – the travel time to the nearest coronary catheterization centre (Royal Columbian Hospital, New Westminster, British Columbia) is between 60 min and 120 min.OBJECTIVES:
To compare access to and use of thrombolysis versus PCI in individuals with ST elevation myocardial infarctions (STEMIs) at CGH.METHODS:
A retrospective chart review was conducted on patients who presented to the emergency department at CGH with STEMIs between January 1, 2004, and December 31, 2005. Of the 67 patients who had a STEMI during this time period, 40 patients met inclusion criteria, of whom, 32 received thrombolytics and eight received PCI.RESULTS:
The average door-to-thrombolysis time was 46 min (95% CI 32 min to 60 min). A door-to-thrombolysis time of less then 30 min was achieved in 15 of 32 patients (47%). The average door-to-balloon time was 186 min (95% CI 166 min to 206 min). A door-to-balloon time of less than 90 min was not achieved in any of the eight patients who received PCI.CONCLUSION:
CGH did not meet the American Heart Association guidelines for a door-to-balloon time of less than 90 min. 相似文献9.

Objective
To characterize risk profile of acute coronary syndrome (ACS) patients in different age groups and compare management provided to in-hospital outcome.Design
Prospective multi-hospital registry.Setting
Seventeen secondary and tertiary care hospitals in Saudi Arabia.Patients
Five thousand and fifty-five patients with ACS. They were divided into four groups: ⩽40 years, 41–55 years, 56–70 years and ⩾70 years. Main outcome measures: prevalence, utilization and mortality.Results: Ninety-four percent of patients <40 years compared to 68% of patients >70 years were men. Diabetes was present in 70% of patients aged 56–70 years. Smoking was present in 66% of those <40 years compared to 7% of patients >70 years. Fifty-three percent of the patients >70 years and 25% of those <40 years had history of ischemic heart disease. Sixty percent of patients <40 years presented with ST elevation myocardial infarction (STEMI) while non-ST elevation myocardial infarction was the presentation in 49% of patients >70 years. Thirty-four percent of patients >70 years compared to 10% of patients <40 years presented >12 h from symptom onset with STEMI. Fifty-four percent of patients >70 compared to 64–71% of those <70 years had coronary angiography. Twenty-four percent of patients >70 compared to 34–40% of those <70 years had percutaneous coronary intervention. Reperfusion shortfall for STEMI was 16–18% in patients >56 years compared to 11% in patients <40 years. Mortality was 7% in patients >70 years compared to 1.6–3% in patients <70 years. For all comparisons (p < 0.001).Conclusions
Young and old ACS patients have unique risk factors and present differently. Older patients have higher in-hospital mortality as they are treated less aggressively. There is an urgent need for a national prevention program as well as a systematic improvement in the care for patients with ACS including a system of care for STEMI patients. For older patients there is a need to identify medical as well as social factors that influence the therapeutic management plans. 相似文献10.

Background
Chronic hepatitis C (CHC) is a global infection. In Saudi Arabia, the prevalence of CHC is declining due to the implementation of a blood screening program. However, CHC still remains a leading cause of liver cirrhosis and hepatocellular carcinoma.Objectives
This is a retrospective study of CHC patients at the King Abdul Aziz University Hospital, Jeddah, Saudi Arabia.Patients and Methods
Out of a total of 291 CHC patients from the hepatology clinic at King Abdul Aziz University hospital, Jeddah, 279 patients were included in the present study. They were primarily male (152, 54.5%), with a mean age of 50.41 ± 1.72 years. The majority of patients were either Saudi (108, 38.7%) or Egyptian (60, 21.5%). A total of 61 patients received combination treatment with pegylated interferon and ribavirin, and one patient with sickle-cell anemia received pegylated INF monotherapy. Demographic, clinical and laboratory features of the CHC patients, and their responses to treatment were studied.Results
Decompensated cirrhosis was documented in 60 patients (21.5%), and hepatocellular carcinoma in 14 (5%). The mean level of serum alanine aminotransferase was 83.6 ± 231 u/L. The predominant genotype among the 70 patients tested, was genotype 4, followed by genotype 1 (39 and 18 patients, respectively). The sustained viral response (SVR) rate was 82.99%. The main predictive factors for SVR were baseline HCV viral load and rapid virologic response (RVR). The mean duration of follow-up was 4.2 ± .85 years. There were 24 patients who had liver disease-related mortality.Conclusions
our data showed that 22% of CHC patients progress to cirrhosis and another 22% had treatment. Liver related mortality was more common in patients with advanced cirrhosis. 相似文献11.

Background
Acute coronary syndrome (ACS) is one of the main causes of morbidity and mortality in the modern world. A sedentary lifestyle, present in 85% of the Brazilian population, is considered a risk factor for the development of coronary artery disease. However, the correlation of a sedentary lifestyle with cardiovascular events (CVE) during hospitalization for ACS is not well established.Objective
To evaluate the association between physical activity level, assessed with the International Physical Activity Questionnaire (IPAQ), with in-hospital prognosis in patients with ACS.Methods
Observational, cross-sectional, and analytical study with 215 subjects with a diagnosis of ACS consecutively admitted to a referral hospital for cardiac patients between July 2009 and February 2011. All volunteers answered the short version of the IPAQ and were observed for the occurrence of CVE during hospitalization with a standardized assessment conducted by the researcher and corroborated by data from medical records.Results
The patients were admitted with diagnoses of unstable angina (34.4%), acute myocardial infarction (AMI) without ST elevation (41.4%), and AMI with ST elevation (24.2%). According to the level of physical activity, the patients were classified as non-active (56.3%) and active (43.7%). A CVE occurred in 35.3% of the cohort. The occurrence of in-hospital complications was associated with the length of hospital stay (odds ratio [OR] = 1.15) and physical inactivity (OR = 2.54), and was independent of age, systolic blood pressure, and prior congestive heart failure.Conclusion
A physically active lifestyle reduces the risk of CVE during hospitalization in patients with ACS. 相似文献12.
Aim
Cardiovascular disease is becoming the lead cause of mortality and morbidity worldwide, and developing countries are the main contributors to this trend. Saudi Arabia, which is considered a rapidly developing country, faces progressive urbanization and the adoption of a westernized lifestyle, factors which contribute to the rising burden of cardiovascular disease. Our study evaluates the prevalence of coronary risk factors and predicts hard coronary artery events over 10 years in an urban Saudi cohort.Methods
A cross-sectional observational study was conducted on a Saudi population. The study involved Saudi subjects aged more than 20 years without a history of coronary heart disease. Demographic variables and hard coronary events (HCE) risk factors were measured. Each subject’s 10-year HCE risk was estimated by means of the Framingham Risk Score (FRS).Results
A total of 4932 subjects (2215 men and 2717 women) were examined, the majority (85%) of whom were less than 40 years old. The risk of developing HCE within the next 10 years was low in 92.6% of subjects, intermediate in 3.2% and high in 4.1%. On considering diabetes as coronary heart disease (CHD) risk-equivalent, 26% of subjects were at high risk for hard coronary events in 10 years. The HCE risk progressively increased with age and was higher in men.Conclusions
Our study, the first to estimate the 10-year risk of HCE among adults in an emerging country, determined that a significant proportion of a younger aged population is at risk for the development of hard coronary events. Public awareness programs to control risk factors are warranted. 相似文献13.

Background/Aims
Endoscopic retrograde cholangiopancreatography (ERCP) is considered a high-risk procedure in patients with previous acute coronary syndrome (ACS); however, clinical studies are rare in the literature. The aim of this study was to investigate the safety and efficacy of ERCP in patients with previous ACS.Methods
We retrospectively reviewed the medical records of patients with previous ACS who underwent ERCP between January 2007 and August 2012. The clinical characteristics, ERCP diagnoses, treatment results, and complications were analyzed.Results
Fifty patients underwent ERCP an average of 41.6 months after ACS. The most common indication for ERCP was calculous cholangitis. After deep biliary cannulation, endoscopic sphincterotomy, biliary stone removal and endoscopic biliary drainage were successfully performed. Immediate postsphincterotomy bleeding occurred in seven patients, which was successfully controlled using endoscopic therapy. Elevation of cardiac troponin I levels were observed in three patients (6%) before ERCP, and all of these patients were diagnosed with pancreatobiliary disease combined with recurrent ACS, which was treated with coronary artery stent insertion (n=2) and balloon angioplasty (n=1).Conclusions
Therapeutic ERCP is effective and safe in patients with previous ACS. Cardiac troponin I elevation should be considered a warning sign for recurrent ACS in patients who undergo ERCP. 相似文献14.

Background/Aims:
Despite the remarkable increase in the incidence of Crohn''s disease among Saudis in recent years, data about Crohn''s disease in Saudi Arabia are scarce. The aim of this study was to determine the clinical epidemiology and phenotypic characteristics of Crohn''s disease in the central region of Saudi Arabia.Patients and Methods:
A data registry, Inflammatory Bowel Disease Information System (IBDIS), was used to register Crohn''s disease patients who presented to the gastroenterology clinics in four tertiary care centers in Riyadh, Saudi Arabia between September 2009 and February 2013. Patients’ characteristics, disease location, behavior, age at diagnosis according to the Montreal classification, course of the disease, and extraintestinal manifestation were recorded.Results:
Among 497 patients with Crohn''s disease, 59% were males with a mean age at diagnosis of 25 years [95% Confidence Interval (CI): 24-26, range 5-75 years]. The mean duration from the time of complaint to the day of the diagnosis was 11 months, and the mean duration of the disease from diagnosis to the day of entry to the registry was 40 months. Seventy-seven percent of our patients were aged 17-40 years at diagnosis, 16.8% were ≤16 years of age, and 6.6% were >40 years of age. According to the Montreal classification of disease location, 48.8% of patients had ileocolonic involvement, 43.5% had limited disease to the terminal ileum or cecum, 7.7% had isolated colonic involvement, and 16% had an upper gastrointestinal involvement. Forty-two percent of our patients had a non-stricturing, non-penetrating behavior, while 32.8% had stricturing disease and 25.4% had penetrating disease.Conclusion:
Crohn''s disease is frequently encountered in Saudi Arabia. The majority of patients are young people with a predilection for males, while its behavior resembled that of western societies in terms of age of onset, location, and behavior. 相似文献15.

Background
Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS).Objective
To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS.Methods
Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged <65 years, hospitalized with diagnosis of ACS. The Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI), which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE), emotional distancing (EmD), dehumanization (De) and professional fulfillment (PF). The Lipp’s Stress Symptoms Inventory for Adults (LSSI) was applied to evaluate global stress.Results
Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%.Conclusion
We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital. 相似文献16.
Objective To explore the treatment, procedure related risks, and outcomes of patients older than 90 years of age undergoing cardiac catheterization. Methods We retrospectively studied 32 patients ≥ 90 years (93.0 ± 1.2 years) who underwent cardiac catheterisation in a tertiary specialist hospital (0.2% of 14,892 procedures during three years). The results were compared to a patient cohort younger than 90 years of age. Results Baseline characteristics revealed a higher prevalence of diabetes (P < 0.001), chronic obstructive pulmonary disease (P < 0.04), previous myocardial infarction (P < 0.02), and complex coronary anatomy (SYNTAX score 33 vs. 19) in nonagenarians. Patients < 90 years of age showed more hyperlipidemia (P < 0.01) and previous percutaneous coronary interventions (P < 0.015). Nonagenarians underwent coronary angiography more often for acute coronary syndrome (ACS) (P < 0.003), were presented more often in cardiogenic shock (P < 0.003), and were transferred faster to coronary angiography in cases of ACS (P < 0.0001). The observed in-hospital mortality rate (13% study group vs. 1% control group; P < 0.003) in nonagenarians was lower than the calculated rate of thrombolysis in myocardial infarction (TIMI) and global registry of acute cardiac events (GRACE) mortality and strongly influenced by the severity of clinical presentation and the presence of co-morbidities. Conclusions Despite the common scepticism that cardiac catheterisation exposes patients ≥ 90 years to an unwarranted risk, our data demonstrate an acceptable incidence of complications and mortality in this group of patients. 相似文献

Background
Previous studies have shown that coronary plaque composition plays a pivotal role in plaque instability, and imaging modalities and serum biomarkers have been investigated to identify vulnerable plaque. Virtual histology IVUS (VH-IVUS) characterizes plaque components as calcified, fibrotic, fibrofatty, or necrotic core. C-reactive protein (hsCRP) is an independent risk factor and a powerful predictor of future coronary events. However, a relationship between inflammatory response indicated by CRP and plaque characteristics in ACS patients remains not well established.Objective
To determine, by using VH-IVUS, the relation between coronary plaque components and plasma high-sensitivity CRP levels in patients with acute coronary syndromes (ACS).Methods
52 patients with ACS were enrolled in this prospective study. Electrocardiographically-gated VH-IVUS were performed in the culprit lesion before PCI. Blood sample was drawn from all patients before the procedure and after 24 hours, and hs-CRP levels were determined.Results
Mean age was 55.3±4.9 years, 76.9% were men and 30.9% had diabetes. Mean MLA was 3.9±1.3 mm2, and plaque burden was 69±11.3%, as assessed by IVUS. VH-IVUS analysis at the minimum luminal site identified plaque components: fibrotic (59.6±15.8%), fibrofatty (7.6±8.2%), dense calcium (12.1±9.2%) and necrotic core (20.7±12.7%). Plasma hs-CRP (mean 16.02±18.07 mg/L) did not correlate with necrotic core (r=-0.089, p = 0.53) and other plaque components.Conclusions
In this prospective study with patients with ACS, the predominant components of the culprit plaque were fibrotic and necrotic core. Serum hs C-reactive protein levels did not correlate with plaque composition. 相似文献18.

Background/Aim:
To determine the epidemiology of Crohn''s disease (CD) in an outpatient clinic and compare it with data previously reported from different centers in the Kingdom of Saudi Arabia and outside.Materials and Methods:
The medical records of all patients with CD seen in the clinic in the period from January 1993 through December 2007 were reviewed. The demographic, clinical data and methods of diagnosis were retrieved.Results:
Over a period of 15 years, we saw 133 Saudi patients with CD. They were predominantly young, with a median age of 26.2 years and male preponderance (2.3:1). The final diagnosis was established within 1 week of presentation in 47% of the patients. The leading symptoms were abdominal pain (88%), diarrhea (70%), bloating (61%), rectal bleeding (50%), weight loss (33%), constipation (24%) and perianal disease (23%). The diagnosis was established by endoscopy and histopathology. Ileocecal involvement was encountered in 40% of the patients.Conclusion:
From the current study, it is obviously possible to diagnose a large proportion of patients with CD in a gastroenterology outpatient clinic. The data revealed a strikingly increased incidence of CD in a mainly young Saudi population in the past few years. 相似文献19.

Background
There is limited available information for treatment of acute coronary syndrome (ACS) with respect to outcomes, therapeutic agents and treatment practices. Our retrospective registry study collected and evaluated varying anti-platelet treatment strategies and outcomes of ACS patients who were admitted to 9 different tertiary care hospitals in India. This study was carried out to provide an insight to anti-platelet treatment patterns and analyze outcomes of ACS patients in India.Methods
All the relevant data, including anti-platelet treatment strategies, outcomes and patient treatment compliance were collected from 500 ACS (defined as STEMI, NSTEMI and unstable angina [UA]) cases from January 2007 to December 2009. These ACS cases were randomly collected from the hospital records and included in the analysis. The patient follow up data was acquired either from the hospital records or via telephonic contact for a period of one year following the event.Results
Out of 500 ACS patients, 59.8% had UA/NSTEMI and 40.2% had STEMI. On hospital admission, aspirin, clopidogrel, statins, beta-blockers and angiotensin converting enzyme inhibitors (ACE-Is) were used by 83%, 83%, 68%, 43.2% and 31.6% patients, respectively. On discharge, aspirin, clopidogrel, statins and beta-blockers were used by 90.2%, 88%, 80.6%, and 59% patients, respectively. The average patient compliance to statins, clopidogrel and aspirin was recorded as 74.28%, 69.7% and 68.66%, respectively during discharge and follow-up visits. Greater than 50% of ACS patients after discharge were lost to follow-up and as a result there was significant drop in the number of clinical events reported.Conclusion
This pilot study conducted in tertiary care centers in India showed that patients with ACS were more often diagnosed with UA/NSTEMI as compared to STEMI and reported maximum compliance to statins, clopidogrel and aspirin after discharge over 1 year follow-up. More ACS patients were lost to follow up that resulted in low reporting of clinical outcomes, following discharge upto 1 year. 相似文献20.
