Heart failure in Nigerian hypertensives
Insights
Heart failure is more common in Nigerian hypertensives with low socioeconomic status, low hematocrit, low serum albumin, and heavy alcohol consumption. Other factors besides hypertension precipitate heart failure.
Area of Science:
- Cardiology
- Public Health
- Internal Medicine
Background:
- Hypertension is a significant risk factor for heart failure.
- The incidence of heart failure among hypertensive patients in Nigeria is notably high.
- Understanding contributing factors beyond hypertension is crucial for effective management.
Purpose of the Study:
- To investigate factors associated with heart failure in Nigerian hypertensive patients.
- To identify demographic, clinical, and lifestyle factors influencing heart failure development.
Main Methods:
- A study of 209 consecutive hypertension cases at University College Hospital, Ibadan, Nigeria.
- Data collection included socioeconomic status, hematocrit, serum albumin, alcohol consumption, and chest X-ray findings.
- Analysis focused on the correlation between these factors and the incidence of heart failure.
Main Results:
- Heart failure was more prevalent in patients of low socioeconomic class.
- Low hematocrit (<30%) and low serum albumin levels were strongly associated with heart failure.
- Heavy alcohol consumption, cardiomegaly, and aortic unfolding on chest X-ray also correlated with increased heart failure risk.
- Age, sex, Hb genotype, obesity, and retinal changes did not significantly influence heart failure development.
Conclusions:
- Hypertension alone does not fully explain heart failure in Nigerian patients.
- Socioeconomic status, hematocrit, serum albumin, alcohol intake, and cardiac structural changes are critical contributing factors.
- These findings highlight the need for a multifactorial approach to prevent and manage heart failure in this population.
Abstract:
A study of 209 consecutive cases of hypertension, seen at the cardiac unit of the University College Hospital, Ibadan, Nigeria, showed that heart failure occurred more commonly in patients who were in the low socio-economic class. All those who had a haematocrit below 30% had heart failure. The lower the serum albumin, the greater the likelihood of developing heart failure. Hypertensives who were heavy alcohol drinkers were very prone to heart failure while a significant proportion of those who had cardiomegaly or cardiomegaly with aortic unfolding on chest x-ray had heart failure. Age, sex, Hb genotype, obesity and retinal changes had no influence on the development of heart failure. It is concluded that there are other factors, besides hypertension, which precipitate heart failure in Nigerian hypertensives. This may be responsible for the high incidence of heart failure among Nigerian with hypertension.
