PREVALENCE OF LEFT VENTRICULAR DIASTOLIC DYSFUNCTION IN PREOPERATIVE VISIT CLINIC

Abstract

Objective: To evaluate the prevalence of left ventricular dysfunction and somerelated factors in patients referred to the preoperative visit clinic.

Methodology: In this cross-sectional study, patients aged above 20 years whounderwent echocardiography after physical examination at Poorsina Hospitalaffiliated to Guilan University of Medical Sciences Iran from January to July 2016.Patients were evaluated in two groups with left ventricular diastolic dysfunctionand without left ventricular diastolic dysfunction. The research inclusion criteriaincluded a lack of history of systolic heart failure and proven heart valvedysfunction, lack of deformity, infection and ulcers in the echo site. Lack ofpatient's willingness to continue the study and poor echocardiography windowwere our exclusion criteria. Then, the data was analyis in SPSS version 16.

Results: Among 399 patients, 175 had no diastolic dysfunction and 224 (56.1%)had diastolic dysfunction, 200 patients (89.3%)had grade 1 diastolic dysfunctionand 24 patients (10.7%) had grade 2 dysfunction. There was a significantdifference in the frequency distribution of sex between the two groups (p=0.001), so that the odd ratio of this dysfunction was two times more in femalecompared to male. There was a significant difference between the two groups inthe mean age and age ranges (p= 0.0001), with increased prevalence ofdiastolic dysfunctions in elderly. The mean BMI in the affected group was higherthan that in non-affected group. (p = 0.034). There was a statistically significantdifference between two groups with and without left ventricular diastolicdysfunction in terms of the history of diabetes (p= 0.0001).

Conclusion: Given the high prevalence of diastolic dysfunction in the communityof patients, who were candidate for surgery especially at higher ages as well aspatients with high risk factors (female sex, diabetes, hypertension and medicineusers), echocardiography was recommended to investigate the preoperativeheart diastolic dysfunction.
