Insights
A significant number of hypertensive African black patients exhibit abnormal left ventricular geometry. Blood pressure levels directly correlate with changes in left ventricular mass, highlighting the impact of hypertension on cardiac structure.
Area of Science:
- Cardiology
- Hypertension Research
- Echocardiography
Context:
- Hypertension is a prevalent condition globally, particularly in African populations.
- Left ventricular remodeling is a common consequence of sustained hypertension.
- Understanding the specific patterns of remodeling in African black hypertensive patients is crucial for targeted interventions.
Purpose:
- To determine the prevalence of different types of echocardiographic left ventricular remodeling.
- To identify the determinants of left ventricular remodeling in this population.
- To investigate the relationship between blood pressure and left ventricular geometry.
Summary:
- A transversal study of 524 hypertensive patients in Côte d'Ivoire revealed that 29% had cardiac remodeling.
- Concentric remodeling was observed in 14.7% of women and 15.7% of men; concentric hypertrophy in 6% and 10.3%, respectively; and eccentric hypertrophy in 7.6% and 3.7%.
- Systolic and diastolic blood pressure levels were significantly correlated with left ventricular mass indexed to body surface area.
Impact:
- The study highlights a significant prevalence of abnormal left ventricular geometry in hypertensive African black individuals.
- It confirms the association between elevated blood pressure and alterations in left ventricular geometry.
- Findings underscore the importance of blood pressure control in preventing adverse cardiac remodeling in hypertensive patients.
Aim:
To determine the prevalence and determinants of different types of echocardiographic left ventricular remodeling in African black hypertensive patients.
Patients And Methods:
A transversal descriptive study was conducted from January 1, 2015, to March 31, 2016, in the external explorations department of the Abidjan Heart Institute-Côte d'Ivoire. Transthoracic cardiac echo-graphs were performed in 524 (251 women) hypertensive subjects according to the American Society of Echocardiography convention.
Results:
Twenty-nine percent of hypertensive patients had cardiac remodeling (in women and men, respectively, concentric remodeling 14.7 % and 15.7 %; concentric hypertrophy 6 % and 10.3 %; eccentric hypertrophy 7.6 % and 3.7 %). Only systolic and diastolic blood pressure levels were significantly correlated with left ventricular mass indexed to body surface area.
Conclusion:
This study showed a significant proportion of hypertensives with abnormal left ventricular geometry and confirmed the relationship between blood pressure level and left ventricular geometry change.
