Impact of potentially lethal ventricular arrhythmias on long-term outcome in patients with chronic heart failure

Background  Potentially lethal ventricular arrhythmias (PLVAs) occur frequently in survivors after acute myocardial infarction and are increasingly recognized in other forms of structural heart diseases. This study investigated the prevalence and prognostic significance of PLVAs in patients with chronic heart failure (CHF).

Methods  Data concerning demographics, etiology of heart failure, NYHA functional class, biochemical variables, electrocardiographic and echocardiographic findings, and medical treatments were collected by reviewing hospital medical records from 1080 patients with NYHA II–IV and a left ventricular (LV) ejection fraction ≤45%. PLVAs were defined as multi-focal ventricular ectopy (>30 beats/h on Holter monitoring), bursts of ventricular premature beats, and nonsustained ventricular tachycardia. All-cause mortality, sudden death, and rehospitalization due to worsening heart failure, or cardiac transplantation during 5-year follow-up after discharge were recorded.

Results  The occurrence rate of PLVAs in CHF was 30.2%, and increased with age; 23.4% in patients <45 years old, 27.8% in those between 45–65 years old, and 33.5% in patients >65 years old (P=0.033). Patients with PLVAs had larger LV size and lower ejection fraction (both P <0.01) and higher all-cause mortality (P=0.014) during 5-year follow-up than those without PLVAs. Age (OR 1.041, 95% CI 1.004–1.079, P=0.03) and LV end-diastolic dimension (OR 1.068, 95% CI 1.013–1.126, P=0.015) independently predicted the occurrence of PLVAs. And PLVA was an independent factor for all-cause mortality (RR 1.702, 95% CI 1.017–2.848, P=0.031) and sudden death (RR 1.937, 95% CI 1.068–3.516, P=0.030) in patients with CHF.

Conclusion  PLVAs are common and exert a negative impact on long-term clinical outcome in patients with CHF.

Impact of depressed left ventricular function on outcomes in patients with three-vessel coronary disease undergoing percutaneous coronary intervention

Background  Patients with multivessel coronary artery disease and depressed left ventricular ejection fraction (LVEF) represent a high risk group of patients for coronary revascularization. There are limited data on percutaneous coronary intervention treatment in this population.  

Methods  Among a cohort of 4335 patients with three-vessel disease with or without left main disease undergoing percutaneous coronary intervention, 191 patients had LVEF <40% (low ejection fraction (EF)) and 4144 patients had LVEF ≥40%. In-hospital and long-term outcomes were examined according to LVEF.

Results  The estimated two-year rates of major adverse cardiac events, cardiac death, and myocardial infarction were significantly higher in the low EF group (19.64% vs. 8.73%, Log-rank test: P <0.01; 10.30% vs. 1.33%, Log-rank test: P <0.01, and 10.32% vs. 2.28%, Log-rank test: P <0.01 respectively), but there was no difference in the rates of target vessel revascularization (6.18% vs. 6.11%, Log-rank test: P=0.96). Using the Cox proportional hazard models, LVEF <40% was a significant risk factor for cardiac death, myocardial infarction, and major adverse cardiac events (OR (95% CI): 4.779 (2.369–9.637), 2.673 (1.353–5.282), and 1.827 (1.187–2.813) respectively), but was not a statistically significant risk factor for target vessel revascularization (OR (95% CI): 1.094 (0.558–2.147)).

Conclusion  Among patients undergoing percutaneous coronary intervention for multivessel coronary artery disease, left ventricular dysfunction remains associated with further risk of cardiac death in-hospital and during long-term follow-up.

Clinical and angiographic correlates of left ventricular dysfunction in patients with three vessel coronary disease

Background  Among patients with advanced multivessel coronary disease, left ventricular (LV) function is widely variable, and clinical and angiographic correlates of ventricular dysfunction remain to be defined.   

Methods  Among 73 339 patients undergoing diagnostic cardiac catheterization at a single center in China, patients with left ventriculographic assessment were identified with three-vessel coronary disease with or without left main involvement. Clinical and angiographic characteristics were examined among patients with normal or varying extent of LV dysfunction, and predictors of LV impairment (ejection fraction (EF): <25%, 25%–40% or >40%) were determined.

Results  Among 11 950 patients identified with three-vessel coronary disease, the sample distribution of LVEF was >40%, n=10 776; 25%–40%, n=948; <25%, n=226. Patients with reduced LV function (<40%) more commonly were male and had a history of myocardial infarction (MI), diabetes or unstable angina. Hypertension was more frequent in those with LVEF ≥40%. In a multivariate Logistic regression analysis, prior MI (odds ratio (OR), 3.37; 95% confidence interval (CI), 2.96–3.84) was most predictive of LVEF <40%, followed by male gender, diabetes, and presentation with unstable angina. For LVEF <25%, only prior MI was identified as a significant correlate of severe LV dysfunction (OR  4.06, 95% CI 3.06–5.39). Following exclusion of patients with previous MI (n=7416), male gender and diabetes were predictive of LVEF <40%, yet presentation with unstable angina was the only factor significantly associated with LVEF <25%.

Conclusion  Among individuals identified with three-vessel coronary disease with or without left main involvement, previous MI was the most significant risk factor of LV dysfunction.

Prevalence and risk factors for left ventricular hypertrophy and left ventricular geometric abnormality in the patients with hypertension among Han Chinese

Background  Left ventricular hypertrophy (LVH) and geometric abnormality are associated with morbidity and mortality of cardiovascular disease and stroke. Hypertension is the major cause of LVH. Yet the prevalence and other risk factors of LVH and geometric abnormality in Chinese hypertensive population are unknown. The objective of this study was to investigate the prevalence and risk factors of LVH and geometric abnormality in community-based Chinese hypertensive population.

Methods  The study was a community-based cross-sectional study, and comprised 4270 hypertension patients with integrated clinical and echocardiographic data. Left ventricular mass was measured by transthoracic echocardiography. LVH was diagnosed by using the criteria of over 49.2 g/m^2.7 for men and 46.7 g/m^2.7 for women. LV geometric patterns (normal, concentric remodeling, concentric or eccentric hypertrophy) were calculated according to LVH and relative wall thickness. Logistic regression model was used to determine the odds ratio (OR) and 95% confidence intervals (CI) of the risk factors of LVH.

Results  The prevalence of LVH was 42.7% in 4270 hypertensive patients, with 37.4% in males and 45.4% in females, respectively. The prevalence of concentric remodeling, concentric or eccentric hypertrophy was 24.7%, 20.2%, and 22.6%, respectively. In Logistic regression model, female (OR 1.3, 95%CI 1.1–1.5, P <0.01), age (OR 1.02, 95%CI 1.01–1.03, P <0.01), body mass index (OR 1.2, 95%CI 1.15–1.20, P <0.01), systolic blood pressure (OR 1.02, 95%CI 1.01–1.03, P <0.01), and serum triglyceride (OR 1.10, 95% CI 1.00–1.20, P <0.01) were risk factors of LVH. Female, age, body mass index, systolic blood pressure and serum triglyceride were also risk factors of left ventricular geometric abnormality.

Conclusions  The echocardiographic LVH is the major complication of patients with hypertension in rural area of China, especially for women. To effectively treat hypertension, weight loss and control of serum triglyceride may help to prevent LVH in hypertensive population.

Incidence and predictors of definite stent thrombosis after coronary stent implantation

Background  Coronary stents are widely used in percutaneous coronary intervention (PCI) procedures. We aimed to explore the incidence, predictors and characteristics of stent thrombosis (ST) after coronary stent implantation in routine clinical practice.

Methods  From data of 18 063 consecutive patients who underwent successful stent implantation in Shenyang Northern Hospital from 2004 to 2010, we identified patients with definite ST (n=140) and control patients (n=280) matched on age, diagnosis, sex, current antiplatelet medication and stent type. The incidence, predictors and characteristics of ST after coronary stent implantation were investigated.

Results  The incidence of angiographically confirmed ST was 0.78% (140/18 063). The time distribution of ST was acute in 43 (30.7%), subacute in 50 (35.7%), and late in 47 (33.6%) patients. Binary Logistic regression analysis identified the angiotensin-converting enzyme inhibitor (ACEI) (odds ratio (OR)=0.472, 95% CI: 0.276–0.807, P=0.006) and heparin (OR=0.477, 95% CI: 0.278–0.819, P=0.007) were associated with an reduced risk of cumulative ST. Stent length (OR=1.042, 95% CI: 1.026–1.058, P <0.001), serum creatinine total (OR=1.020, 95% CI: 1.004–1.035, P=0.04), cholesterol (OR=1.267, 95% CI: 1.021–1.573, P=0.032), glucose (OR=1.086, 95% CI: 1.002–1.176, P=0.044), and platelet aggregation (OR=1.113, 95% CI: 1.075–1.154, P <0.001) were associated with an increased risk of cumulative ST.

Conclusion ST is associated with longer stent length and higher level of total cholesterol, glucose and platelet aggregation.

Management status of type 2 diabetes mellitus in tertiary hospitals in Beijing: gap between guideline and reality

Background  Diabetes has become one of the most common chronic diseases and the third leading cause of death in China. Many programs have been initiated at national and local levels to address the illness. However, the effect of these programs in daily outpatient clinics is still unclear. The objective of this study was to investigate the management status of type 2 diabetes mellitus (T2DM) and factors associated with it in diabetes clinics of tertiary hospitals in Beijing.

Methods  A cross-sectional survey was conducted in six tertiary hospitals in Beijing. Control criteria were defined based on 2007 China guideline for type 2 diabetes (CGT2D).

Results  A sample of 1151 patients, age (60.8±9.2) years, and with a median disease duration of 7.3 years was included. The hemoglobin A1c (HbA1c) mean level was (7.15±1.50)%, the percentage of patients achieving the targets for HbA1c was 37.8%, blood pressure 65.6%, triglyceride (TG) 48.8%, high-density lipoprotein (HDL) 59.2%, low-density lipoprotein (LDL) 34.0%, and total cholesterol (TC) 42.0%. The factors independently associated with glycemic control were diabetes duration (odds ratio (OR) = 0.95; 95% confidence interval (CI): 0.919–0.982, P <0.01), body mass index (BMI) (OR=0.914, 95% CI: 0.854–0.979, P=0.01) and smoking (OR=0.391, 95% CI: 0.197–0.778, P <0.01). The factors independently associated with blood pressure control were BMI (OR=0.915, 95% CI: 0.872–0.960, P <0.01) and male gender (OR=0.624, 95% CI: 0.457–0.852, P <0.01). The factor independently associated with LDL control was education level (OR=1.429, 95% CI: 1.078–1.896, P=0.013).

Conclusions  The management status of T2DM patients in tertiary hospitals in Beijing has improved remarkably. However, there is still room for further improvement to reach the guideline target. Long diabetes duration, high BMI, smoking, male gender and low education level were independently associated with poor metabolic control.
