Introduction: monitoring of chronic heart failure requires control of heart rate (HR), which increases morbidity and mortality in patients with chronic heart failure (HF) when uncontrolled (high). This is why in this study we aimed to assess the heart rate control of patients with stable chronic heart failure in a hospital setting.
Methods: we conducted a hospital-based cross-sectional analytical study in the city of Douala. Outpatients aged at least 18 years, suffering from chronic CHF with stable signs and symptoms (not requiring hospitalization) for at least one month; having given their informed consent were selected. Heart rate, sociodemographic, anthropometric and haemodynamic characteristics were collected. An uncontrolled heart rate was defined as a pulse rate ≥ 70 bpm taken repeatedly at rest.
Results: a total of 123 patients with chronic stable heart failure were selected with a mean age of 65 ± 10 years. The sex ratio was 1.2 with males predominating (54.57%; 67/123). Of the cardiovascular risks, we found that hypertension was the most prevalent, followed by obesity and dyslipidaemia. As aetiology of heart failure, dilated cardiomyopathy was the most represented (94.30%), followed by hypertensive (61%) and ischemic heart disease (8.10%). A high proportion of participants had an uncontrolled heart rate (57/123; 46.3%). Low monthly income was a risk factor associated with poor heart rate control (p=0.027), whereas stage I dyspnoea, beta-blocker use and good compliance were protective factors associated with poor heart rate control.
Conclusion: heart rate control in patients with chronic heart failure is not optimal. The use of beta-blockers and good compliance with medication could optimise control.
