Echocardiographic and clinical correlations in systemic hyper-tension

Area of Science:

• Cardiology
• Hypertension Research
• Diagnostic Imaging

Background:

• Hypertension can lead to cardiac structural changes.
• Early detection of these changes is crucial for managing hypertensive cardiovascular disease.
• Echocardiography offers a non-invasive method to assess cardiac morphology.

Purpose of the Study:

• To correlate echocardiographic findings with hypertension duration and severity.
• To compare echocardiographic measurements with other diagnostic methods like ECG and chest X-ray.
• To evaluate echocardiography's utility in identifying early cardiac alterations in asymptomatic hypertensive patients.

Main Methods:

• Echocardiographic measurements, including left ventricular wall thickness (LVWT) and left atrial diameter, were performed on 47 asymptomatic hypertensive patients.
• Data were correlated with the duration and severity of hypertension, optic fundoscopic findings, electrocardiographic (ECG) data, and chest roentgenographic (X-ray) measurements.
• Statistical analysis was used to determine correlations between variables.

Main Results:

• Left ventricular wall thickness (LVWT) showed a significant correlation with the duration of hypertension (p <= 0.01).
• Patients with longer hypertension duration (>5 years) exhibited increased LVWT compared to recent hypertensive patients.
• Elevated initial diastolic pressure and hypertensive fundi also correlated with increased LVWT; increased left atrial diameter was associated with longstanding disease.

Conclusions:

• Echocardiography is a sensitive tool for detecting early cardiac structural changes in hypertensive patients.
• LVWT and left atrial diameter are valuable echocardiographic markers that correlate with hypertension duration and severity.
• Echocardiography may aid in the early identification and management of cardiac complications in hypertension.
