CHRONIC HEART FAILURE – ONE-YEAR MORTALITY RATE ACCORDING TO RISK FACTORS

Tasks:To determine one-year mortality of patiens (pts.) with chronic heart failure (CHF) and identify risk factors,which can participate in the increase of this mortality rate.
Set:All pts.with CHF hospitalized in the Cardiology Clinic of Faculty Hospital Brno in the period of 10/04-12/06.Mortality rate of pts.,who died till the date 31.12.2006, was validated.
Results:The total one-year mortality rate reached 14.76%. According to cause of CHF died 91 pts. with coronary heart disease (p=0.87), 11 pts. with dilated cardiomyopathy (p=0.006), 13 pts. with valvular heart disease (p=0.02). In total died 15 pts. with isolated diastolic dysfunction (p=0.89 compared to total number of died), 32 pts. with isolated systolic dysfunction (p=0.40) and 56 pts. with both systolic and diastolic dysfunction (p=0.78). Pts. with NYHA class IV. died in  39.02% compared to patients with NYHA class I-III (p<0.001). Mortality rate of patients with anaemia reached 25.19% in comparison to those without anaemia (11.95%, p<0.001).Hypotensive patients died in 21 cases (p<0.001), patients with affiliated diagnosis of HT in 103 cases (p=0.94).From 367 diabetics died 71 compared to those without DM (70, p<0.001). Mortality rate of pts. with chronic renal failure (CRF) made up 25.75% compared to patients with normal renal functions (8.57%, p<0.001). Patients with lower level of total cholesterol  (TCH) died in 14 cases compared to those with normal TCH (40 cases, p<0.001).
Conclusion: One-year mortality rate of patients with CHF made up 14.76% and we found no statisticaly significant differences in mortality according to causes of CHF,as well as to type of dysfunction.Also hypertension did not increase risk of death of our patients .On the contrary there was statisticaly significant higher one-year mortality in patients with aneamia, lower blood pressure, NYHA class IV.,DM,CRF and low TCH
