[Impact of severe hypertension in acute heart failure in Brazzaville (Congo)]
Insights
Severe hypertension significantly increases the risk of acute heart failure (HF) decompensation. Managing blood pressure is crucial for patients hospitalized with acute HF, alongside adherence to treatment.
Area of Science:
- Cardiology
- Hypertension Research
- Heart Failure Studies
Context:
- Acute heart failure (HF) exacerbations are a leading cause of hospitalization.
- Hypertension is a prevalent cardiovascular risk factor.
- Understanding triggers for HF decompensation is critical for patient management.
Purpose:
- To investigate the specific role of hypertension as a precipitating factor in acute heart failure.
- To quantify the risk associated with severe hypertension in emergency HF admissions.
- To identify other common decompensation factors in acute HF.
Summary:
- This retrospective study analyzed 86 patients hospitalized for acute heart failure.
- Severe hypertension was identified as a significant risk factor, with a relative risk (RR) of 3.75 for decompensation.
- Other identified factors included poor treatment adherence (RR 2.2), heart rhythm disorders, impaired renal function, stroke, and anemia.
Impact:
- Findings highlight the critical importance of controlling hypertension in preventing acute heart failure exacerbations.
- Results underscore the need for vigilant monitoring and management of multiple risk factors in HF patients.
- This research can inform clinical guidelines and improve patient outcomes in acute heart failure care.
Abstract:
This retrospective study to assess the role of hypertension in acute heart failure (HF) reviewed the case records of 86 patients, including 35 men (41%) and 51 women (59%), mean age 55.6 ± 18 years, who were hospitalized for an acute exacerbation of HF. The cardiovascular risk factors considered were hypertension (56%), diabetes (8%), and smoking (13%); 11 patients were alcoholics (13%). HF was global in 71 cases (83%). Among the underlying heart diseases, hypertensive cardiomyopathy was noted in 22 patients (26%) and valvular disease in 17 patients (20%); the precise cause was not elucidated in 40 (47%). A decompensation factor was identified in 53 cases (62%). Among the patients admitted on an emergency basis for acute HF, the relative risk (RR) of severe hypertension (n = 41, 48%) was 3.75 (95% CI: 2.31 to 6.08, p<0.0001), of heart rhythm disorder (n = 25 cases, 29%) 0.96 (95% CI 0.6 to 1.4, p = 0.5), and of poor adherence to standard treatment (n = 16, 18%) 2.2 (95% CI, 1.6 to 2.97, p<0.0001). Other decompensation factors were severely impaired renal function in 8 cases (9%) and stroke and anemia in 6 cases each (7%).
