Association of obesity with in-hospital mortality in patients undergoing coronary intervention (PCI).
J Cardiovascular Dis Jan ;12(4):82-5.

OBJECTIVE:Various studies have demonstrated that obesity is associated with increased morbidity and mortality, as well as with other cardiovascular risk factors i.e. diabetes, hypertension and hyperlipidemia Thus, we studied the association of obesity with in-hospital mortality in patients undergoing coronary intervention (PCI) MATERIAL AND METHODS: In this study, 150 patients (75 obese, 75 non obese) 30 to 70 years of age were enrolled through non-probability, purposive sampling technique from cardiology wards of Punjab Institute of Cardiology, Lahore from March 2015 to March 2016. Body mass index (BMI) was measured and patients with BMI > 30Kg/m2 were taken as obese and patients with BMI < 30Kg/m2 were taken as nonobese. All patients who underwent percutaneous coronary intervention patients were included in the study. Group I constituted obese patients and group II non obese patients, while patients with chronic renal failure (serum creatinine> 1.5 mg/dl), chronic liver disease (Hepatitis B or C positive and shrunken liver on ultrasound) and anemia (hemoglobin < 13 mg/dl in males, <12mg/dl in females), (all assessed on past medical records) were excluded. PCI was done by femoral or radial artery approach under local anaesthesia. Patients were managed post PCI as per hospital protocol. All these cases were followed up till 7 days of post-PCI for in –hospital mortality RESULTS:In our study, 19%(n=14) in obese group and 20%(n=15) in non-obese group were between 30-50 years of age while 81%(n=61) in obese an 79.67%(n=60) were between 51-70 years of age, mean age was calculated as 56.68±7.72 in obese and 56.64±7.63 years in non-obese group, 54.67%(n=41) in obese and 57.3%(n=43) in non-obese group were male while 45.33%(n=34) in obese and 42.7%(n=32) in non-obese group were females, mean body mass index was calculated as 34.87±4.65 kg/m2 in obese and 27.63±5.41 kg/m2 in non-obese group. Association of obesity with in-hospital mortality in patients undergoing PCI was recorded as 1.33%(n=1) in obese and 2.66%(n=2) in non-obese group. CONCLUSION:We concluded that there is no association of obesity with in-hospital mortality in patients undergoing coronary intervention (PCI).
