Journal Title: PARIPEX-Indian Journal of Research - Year 2017, Vol 6, Issue 11
Abstract
Background: Unlike LV,RV function has not been widely studied after anterior myocardial infarction. Objectives: The current study aimed to compare RV function in patients with IWMI & AWMI. Methods: 50 patients consecutively presented to the Emergency Department with chest pain were divided on their electrocardiographic findings.Accordingly,26 patients had inferior MI and 24 had anterior MI.Conventional echocardiographic parameters was acquired at admission and then at the time of discharge then at followup.Student t-test and the chi-square test were respectively used for comparisons of the normally distributed continuous and categorical variables in the two groups. Besides, P < 0.05 was considered to be statistically significant. Results: Out of the 50,52% were male and 48% were female subjects with associated comorbidities of diabetes mellitus in 32% of the patients and hypertension in 44% of patients.78% of patients showed no signs of heart failure,12% in class I, 6% in class II and 2% each in class III and class IV of heart failure.58% of patients had RV dysfunction at admission which reduced to 48% at discharge and which further dropped to 30% at one month follow up.The average duration of hospital stay was 5.6days for patients without RV dysfunction and 6.4% for patients with RV dysfunction.In the IWMI group 61.5% of patients had RV dysfunction and in the AWMI group 54.2% of patients had RV dysfunction. Conclusions: RV dysfunction is also associated with AWMI and patients with RV dysfunction at the time of admission have a longer duration of hospital stay and this RV dysfunction improves dramatically irrespective of LV function improvement.
