The Coexistence of Multiple Cardiovascular Diseases is an Independent Predictor of the 30‐Day Mortality of Hospitalized Patients With Congestive Heart Failure: A Study in Beijing

Congestive heart failure (CHF) has become a major clinical and public health challenge with the aging of the population in China. However, the effect of the coexistence of multiple cardiovascular diseases on the prognosis of hospitalized patients with CHF remains unclear. A comparative analysis was performed to explore the etiology and comorbidities of CHF and in‐hospital mortality in patients with CHF.

Influence of sex on outcomes after percutaneous coronary intervention in patients over 75 years of age with coronary heart disease

Background This study aimed to investigate whether there were sex differences in in-hospital and long-term outcomes for elderly patients over 75 years of age undergoing percutaneous coronary intervention for coronary heart disease. Methods Consecutive patients aged ≥75 years who underwent percutaneous coronary intervention at a single center in the People’s Republic of China from January 2005 to December 2010 were included in this cohort study. Clinical characteristics and in-hospital and long-term outcomes were compared between men and women. Results A total of 465 patients (34.8% women, mean age 78.5±3.2 years) were recruited. Men had a higher prevalence of ST elevation myocardial infarction but were less likely to have heart failure than women (P<0.05). Similar rates of successful in-hospital procedures and deaths were observed in men and women. After a mean follow-up of 3 years, no significant differences were observed between men and women in mortality (12.5% versus 8.0%, P=0.151), myocardial infarction (1.4% versus 2.7%, P=0.368), target vessel revascularization (6.1% versus 4.7%, P=0.540), or cerebral vascular disease (7.9% versus 6.0%, P=0.472). Cox proportional hazards analysis revealed that sex was not independently associated with either in-hospital mortality or long-term mortality. Conclusion In elderly patients over 75 years of age, sex influences the prognosis after percutaneous coronary intervention for coronary heart disease.

Secular trends in the etiology and comorbidity of hospitalized patients with congestive heart failure: A single-center retrospective study.

Objective To assess the secular trends in the etiology and comorbidity of patients hospitalized with congestive heart failure (CHF). Methods Data of 7,319 patients (mean age 59.6 years, 62.1% male) with a primary discharge diagnosis of CHF, hospitalized from January 1, 1993 to December 31, 2007 at the Chinese Peoples Liberation Army (PLA) General Hospital were extracted and analyzed. These patients were divided into three groups according to hospitalization period: 1993–1997 (n = 1623), 1998–2002 (n = 2444), and 2003–2007 (n = 3252). The etiological characteristics and comorbidities were assessed. Results Over the study period, the proportion of patients with ischemic heart disease (IHD) increased from 37.2% during the period 1993–1997 to 46.8% during the period 2003–2007, while that with valvular heart disease (VHD) decreased from 35.2% during the period 1993–1997 to 16.6% during the period 2003–2007 (both P < 0.05). Atrial fibrillation (AF) was the most common comorbidity of heart failure (23.2%, 23.0% and 20.6%, respectively, in the three periods). Compared to that of the period of 1993–1997 with that of, the proportion of patients with myocardial infarction, pneumonia, renal function impairment and hepatic cirrhosis of the period of 2003–2007 increased significantly (P < 0.05) and the proportion of patients with chronic obstructive pulmonary disease and atrial fibrillation decreased significantly (P < 0.05). Conclusions This study implies that IHD has became a more common etiology of CHF, while VHD has deceased as an etiology of CHF in Chinese patients during the last two decades.
