Insights
High ambulatory pulse pressure (APP) in hypertensive patients is linked to adverse cardiac changes. Echocardiography can enhance the prognostic value of APP for cardiovascular risk assessment.
Area of Science:
- Cardiology
- Hypertension Research
- Diagnostic Imaging
Background:
- Wide pulse pressure (PP) is a known cardiovascular risk indicator.
- The prognostic value of ambulatory pulse pressure (APP) in hypertensive patients is less understood.
- This study investigates APP's role in cardiovascular risk.
Purpose of the Study:
- To evaluate the relationship between high APP, atrial volumes, and cardiac function in hypertensive patients.
- To determine if APP can predict cardiovascular risk.
- To assess the utility of echocardiography in conjunction with APP.
Main Methods:
- Observational study of 108 untreated hypertensive patients.
- Ambulatory blood pressure monitoring and echocardiography performed.
- Patients grouped by clinic and ambulatory pulse pressure (>60 mmHg vs. <60 mmHg).
Main Results:
- High APP group showed enlarged left atrial volume, increased left ventricular mass index, and impaired diastolic function.
- Positive correlations found between left ventricular dimensions, left atrial volume, and left ventricular mass index in the high APP group.
- Clinic PP correlated with cardiac parameters only in the high APP group.
Conclusions:
- Elevated APP is a potential predictor of cardiovascular risk in hypertensive individuals.
- Echocardiographic assessment of cardiac function and morphology enhances the prognostic value of APP.
- High APP may indicate underlying cardiac structural and functional changes.
Background:
A wide pulse pressure (PP) can provide important risk assessment information about myocardial infarction, carotid artery atherosclerosis, and global cardiovascular risk. Ambulatory pulse pressure (APP) does not have a well-known prognostic value in hypertensive patients.
Methods:
To evaluate the relationship among high APP, atrial volumes, and cardiac function, an observational study was performed on 108 untreated non-elderly hypertensive patients (mean age 54.23 +/- 7.12). Twenty-four-hour ambulatory blood pressure monitoring, Doppler and echocardiographic measurements of systolic, diastolic function, left and right atrial volumes, left ventricular mass index and dimensions, were performed in subjects with both clinic and APP > 60 mmHg (APP1 Group). A control group of hypertensive selected subjects with both clinic and APP < 60 mmHg was chosen (APP 2 Group).
Results:
The APP1 group showed left atrial volume enlargement, high left ventricular mass index, and impaired diastolic function. A positive correlation was found in the APP1 group results among left ventricular end diastolic diameter (r = 0.39, P < 0.01), left atrial volume (0.38, P < 0.05), and left ventricular mass index (r = 0.33, P < 0.05); clinic PP showed a statistically significant correlation with left atrial volume, left ventricular end diastolic diameter, and left ventricular mass index only in the APP1 group.
Conclusions:
These results suggest that elevated APP can be considered an effective predictor of cardiovascular risk in hypertensive subjects. In these patients echocardiographic evaluation of left ventricular function and morphology can increase the prognostic value of PP.
