Effects of nifedipine on diastolic function in hypertensive patients--an echocardiographic study
1Department of Cardiology, Tongji Hospital, Tongji Medical University, Wuhan.
Insights
Hypertension can cause early heart diastolic dysfunction, which nifedipine treatment may improve. Echocardiography effectively assesses diastolic function using measurements like E wave velocity.
Area of Science:
- Cardiology
- Cardiovascular Physiology
Background:
- Uncomplicated hypertension can lead to cardiac alterations.
- Diastolic dysfunction may precede systolic dysfunction in hypertensive patients.
Purpose of the Study:
- To investigate changes in heart function in hypertensive patients.
- To evaluate the therapeutic effects of nifedipine on diastolic function.
Main Methods:
- M-mode and Doppler echocardiography were utilized.
- Seventy patients with uncomplicated hypertension participated.
- Key measurements included EF slope, EA, EPSS, and E wave velocities.
Main Results:
- Diastolic abnormalities were observed to potentially precede systolic dysfunction.
- Nifedipine demonstrated an ability to improve diastolic function.
- E wave velocities proved particularly useful for rapid diastolic function assessment.
Conclusions:
- Diastolic dysfunction is an early indicator in hypertension.
- Nifedipine offers a potential treatment for improving diastolic function.
- Echocardiographic parameters provide a clinically applicable method for evaluating diastolic function.
Abstract:
This study was undertaken to observe the changes in heart function and evaluate the effects of nifedipine on diastolic function in 70 patients with uncomplicated hypertension by M-mode and Doppler echocardiography. The results showed that diastolic abnormalities in hypertensive patients may precede systolic dysfunction and that nifedipine can improve diastolic function. It is easy and quick to estimate the diastolic function by measuring the EF slope, EA and EPSS, especially the E wave velocities. This method proved to be applicable to clinical practice.
