Relation between left ventricular remodeling and nocturnal blood pressure in the elderly with systemic hypertension
1Division of Cardiology, Tokyo Metropolitan Geriatric Hospital, Itabashi-ku, Japan.
Insights
Elderly hypertensive patients with concentric left ventricular hypertrophy show worse heart function and higher nocturnal blood pressure. This pattern suggests a greater risk for cardiovascular events in these individuals.
Area of Science:
- Cardiology
- Hypertension Research
- Echocardiography
Background:
- Hypertension is a major risk factor for cardiovascular disease.
- Left ventricular hypertrophy (LVH) is a common adaptation to chronic hypertension.
- Different patterns of LVH may have distinct clinical implications.
Purpose of the Study:
- To compare cardiac structure and function in elderly hypertensive patients with different left ventricular hypertrophy patterns.
- To assess the relationship between LVH geometry and nocturnal blood pressure profiles.
- To evaluate the potential cardiovascular risk associated with concentric LVH.
Main Methods:
- Retrospective analysis of echocardiographic data in elderly hypertensive patients.
- Classification of left ventricular hypertrophy patterns (e.g., concentric, eccentric).
- Ambulatory blood pressure monitoring to assess nocturnal blood pressure trends.
Main Results:
- Patients with concentric left ventricular hypertrophy exhibited larger LV mass compared to other patterns.
- Concentric LVH was associated with more impaired diastolic LV function.
- Higher nocturnal blood pressure and reduced nocturnal blood pressure dipping were observed in the concentric LVH group.
Conclusions:
- Concentric left ventricular hypertrophy in elderly hypertensive patients is linked to adverse cardiac remodeling and impaired diastolic function.
- This geometric pattern is associated with unfavorable nocturnal blood pressure profiles.
- Concentric LVH may indicate more severe hypertensive cardiac involvement and an elevated risk for cardiovascular events.
Abstract:
Elderly hypertensive patients with concentric left ventricular (LV) hypertrophy had larger LV mass, more impaired diastolic LV function, higher nocturnal blood pressure (BP), and smaller nocturnal BP reduction than those of patients with other geometric patterns. Patients with concentric LV hypertrophy might have more severe hypertensive cardiac involvement and greater risk for cardiovascular events than those patients with other geometric patterns.
