Prevalence of Left Ventricular Diastolic Dysfunction in Patients with Normal Systolic Function and its Relation with Other Risk Factors from Eastern India.

Impaired diastolic filling of left ventricle may be the important cause of symptoms ranging from mild to severe form of dyspnea with overt features of pulmonary edema which may be wrongly imparted to systolic failure. To study prevalence and severity of diastolic dysfunction and its relation with various risk factors. Methods: Patients from in and out patients department were subjected to detail history, estimation of BMI, blood sugar levels, BP measurement, echocardiographic assessment of cardiac function. Patients of isolated diastolic dysfunction were identified and the degree of diastolic dysfunction was correlated with functional class (NYHA grade) of the patients as well as various risk factors. Results: Out of 400 patients 16 (12.5%) asymptomatic patients had diastolic dysfunction (DD). Severity of diastolic dysfunction increased as the presenting NYHA grade was higher. In NYHA grades III and IV, 59% and 57% of the patients respectively had diastolic dysfunction .DD was significantly associated with diabetes (p<.0001), BMI (p =0.0002), dyslipidemia (p =0.0491), hypertension (p=0.0489). Conclusion: DD is a significant cardiac morbidity. Hypertension, diabetes, dyslipidemia and obesity have significant association with diastolic dysfunction. There is no randomized control trials for treatment for DD. Whether asymptomatic DD needs treatment is not known.
