LEFT VENTRICULAR FAILURE IN CASES OF STEMI

Objective; To determine the frequency of left ventricular failure (LVF) in cases with acute ST elevation MI (STEMI). Methodology: In this descriptive case series study conducted at Sheikh Zayed Hospital, Rahim Yar Khan, Jinnah Hospital, Lahore and Services Hospital, Lahore during July to December 2018. In this study there were total 80 cases of acute STEMI. The case of both genders having age between 35 to 75 years presenting within 24 hours of their clinical symptoms of MI were included. The diagnosis of LVF was made according to Killip classification of class II or more. Results: In this study there were total 80 cases of STEMI out of which were 48 (67%) were males and 32 (33%) females. The mean age was 57.41±6.19 years and mean duration of MI was 5.81±1.28 hours. There were 10 (12.50%) cases of HTN, 15 (21.43%) with DM and 18 (22.50%) were obese. LVF was seen in 35 (43.75%) cases. The age group 56 to 75 years had a significant association with this where 26 (52%) out of 50 cases developed LVF as compared to 9 (30%) out of 30 cases with age 35 to 55 years (p=0.01) as in table 2. None of the co morbid conditions like DM, HTN and obesity found significant association with LVF; however the rate was high in every group with risk factors (table 3). Conclusion; LVF is seen in almost half of the cases presenting with STEMI and it is significantly associated with age group 56 to 75 years. Key words. ACS, STEMI, LVF
