  • Diastolic Dysfunction in Persons with Hypertensive Heart Failure

diastolic dysfunction

INTRODUCTION

There is a growing awareness that congestive heart failure (CHF) caused by a predominant abnormality in diastolic function causes significant morbidity and mortality. In the natural course of hypertensive heart disease progression, diastolic dysfunction appears before systolic dysfunction in hypertensive heart failure. However, there are still some patients who come up with symptoms and signs of heart failure while transiting from diastolic dysfunction to systolic dysfunction. These patients often have combined diastolic and systolic dysfunctions.

Differences exist between diastolic and systolic heart failure in terms of the predominant pathophysiological mechanism of the heart failure (decreased left ventricular [LV] compliance or stiffness), therapeutic approach, and prognosis. The prognosis of patients with diastolic heart failure is said to be less ominous than that for patients with systolic heart failure, but prognosis is definitely worse than that for age-matched control patients.

In spite of these differences between diastolic and systolic heart failure, the distinction between the two cannot easily be made “at the bedside,” even after ECG and chest radiographic examination. This is because the clinical symptoms and signs occur with the same relative frequency in both systolic and diastolic heart failure. online canadian pharmacy

The aim of this study is to determine the prevalence of diastolic dysfunction in Nigerians with hypertensive heart failure and, therefore, the need, if any, to advocate Doppler echocardiography as a routine examination in the evaluation of the patient with hypertensive heart failure.
