The risk factors are important in development of heart failure (HF). The aim of the study was to analyse the smoking habit and other risk factors in patients with HF.
Results: A total of 2203 in-hospital HF patients from CRO-HF Registry were analyzed: 46.7% females-f, 53.3% males-m, median age 76 y, 37.8% preserved LVEF. History of hypertension was recorded in 67.5%, diabetes in 34.4%, ACS in 22.7%, renal failure in 19.2%, COPD in 17.3% and atrial arrhythmia in 53.7% patients. Active smokers were 11.1% (14.8% m, 6.4% f) and 15.6% former smokers (24.9% m, 3.9% f). Smoking was related with COPD. Among HF-COPD patients (19.7% m, 14.7% f, P = 0.009), active smokers was 30.6%, former 24.8% and 13.9% non smokers (P < 0.001). Overweight was 46.3%, obese 25% patients, 51.9% had anaemia, 46.8% azotemia, 32% hyperlipidemia, 79.3% hyperuricemia and 99.8% hyperglycemia. The frequent "triggers" of HF were hypertension-55.5%, arrhythmia-51.3%, valvular heart disease-32.8%, ACS-19.7% and infections-19.6%. In-hospital mortality rate was 13.8%.
Conclusion: Smoking habit had one third, higher body weight two thirds, and anaemia more than half of patients. The frequent concomitant diseases were hypertension, diabetes, ACS, arrhythmia, renal failure and infections. The risk factor correction should be important target in prevention of HF.
