[Myocardial functional dynamics in hypertension based on repeated echocardiographic data]
Insights
Hypertension significantly increases blood pressure and left ventricular myocardial weight over 3-5 years. Some patients experienced reversal of hypertrophic changes, but increased weight correlated with decreased heart contractility.
Area of Science:
- Cardiology
- Hypertension Research
- Cardiac Physiology
Context:
- Arterial hypertension is a prevalent cardiovascular risk factor.
- Longitudinal studies are crucial for understanding disease progression.
- Cardiac remodeling is a known complication of sustained hypertension.
Purpose:
- To investigate the long-term effects of arterial hypertension on blood pressure and cardiac structure/function.
- To assess the prevalence of reversal of hypertrophic changes in hypertensive patients.
- To determine the relationship between left ventricular myocardial weight and cardiac contractility.
Summary:
- This study followed 106 patients with arterial hypertension for 3-5 years, observing significant increases in systolic and diastolic arterial pressure.
- Reversal of hypertrophic changes occurred in 25% of labile and 7% of established hypertension cases.
- Left ventricular myocardial weight increased in 42% (labile) and 60% (established) of patients, with increased weight associated with decreased contractility (Vcf index) in established hypertension.
Impact:
- Findings highlight the progressive nature of hypertension and its detrimental effects on cardiac structure.
- The association between increased myocardial weight and reduced contractility underscores the risk of heart failure in hypertensive individuals.
- Understanding these changes can inform more effective hypertension management strategies to prevent cardiac complications.
Abstract:
A total of 106 patients with arterial hypertension were followed up during 3-5 years. Systolic and diastolic arterial pressure increased significantly. Reversal hypertrophic changes were observed in 25% with labile and in 7% of patients with established hypertension. Increase of left ventricular myocardial weight was observed in 42% and 60%, respectively. Increased myocardial weight in established hypertension was associated with the contractility decrease assessed by Vcf index.
