The prevalence of left ventricular diastolic dysfunction in CHF resulting from systemic hypertension


MM Rahman, ZF Jesmin, SK Chakrovortty, Tahmid Rahman

Introduction: Left ventricular diastolic dysfunction is a major phenomenon in patients with Congestive Heart Failure (CHF). Diastolic dysfunction include alterations of both relaxation and filling, precede alterations of chamber systolic function and can induce symptoms of heart failure even when ejection fraction is normal. As only a few studies had been conducted about left ventricular diastolic dysfunction in CH29-*9-*-*/F in our country so we have arranged this study to know more about the issue. Objective: The major objective of this study was to assess the prevalence of diastolic dysfunction in congestive heart failure resulting from systemic hypertension. Methods: This was a prospective observational study was carried out in Shaheed Shaikh Abu-Naser Specialized Hospital, Khulna, Bangladesh during the period from January 2017 to December 2018. Sixty patients with systemic hypertension who had recently experienced CHF with normal, EF≥50% and no clinical history of ischaemic cardiomyopathy were the study population. The patients were divided into two groups according to the degree of echocardiographic hypertrophy. In Group I there were 32 patients with a ventricular mass/volume ratio >1.8 and in Group II there were 28 patients with a ratio <1.8. Result: Among the first selected 290 cases with CHF 60 were with diastolic dysfunction. So ratio was 20.70%. Among the study population with CHF as well as left ventricular dysfunction, male are dominating and the ratio was 58.33% (35). Among total participants the highest ratio of diastolic dysfunction was found in 61-70 years’ age group. So age is a major factor here. The highest suffered portion of diastolic dysfunction is 38.33% and their duration was <5 years. Second highest ratio was 25% and their duration was 6-10 years. Then 20% (11-15 years), 11.67% (16-20 years) and lastly 5% and their duration was >20 years. Conclusion: Left ventricular diastolic dysfunction undoubtedly is a major factor in patients with Congestive Heart Failure (CHF) and demand more attention in cardiac treatment. The findings of this study may help in further studies and in the treatment of CHF but as it was a single centered study with a small sized sample so this result may not reflect the exact scenario of the whole country.
