Dyslipidemia as a risk factor for acute myocardial infarction in postmenopausal women: An observational study
Abstract
Objective: This study has evaluated risk factors, especially dyslipidemia, for an acute myocardial infarction (AMI) in postmenopausal women. Materials and Methods: This was a hospital-based, observational, single-center study among 100 postmenopausal women admitted to the medicine ward with AMI. They were categorized based on lipid profile groups, viz., dyslipidemic group and non-dyslipidemic group. All clinical parameters were studied between the groups. Results: Among anthropometric profiles, in the comparison of mean height (cm), weight (kg), body mass index (BMI) (kg/m2), and waist circumference (WC) (cm) for the dyslipidemic group and non-dyslipidemic group, only WC was statistically significant (P < 0.001). Most patients were hospitalized between 6 and 12 h after the onset of symptoms. At the time of hospitalization, most patients from both groups were observed to have diabetes and hypertension with poor control of postprandial blood sugar, glycated hemoglobin, and diastolic blood pressure (DBP) (P < 0.05). The dyslipidemic group’s mean C-reactive protein was higher (P < 0.05). The comparison of mean total cholesterol, triglyceride (TG), low density lipoprotein-cholesterol in mg/dL, and TG: high density lipoprotein was significantly increased (P < 0.001), while high density lipoprotein-cholesterol (mg/dL) was significantly decreased (P < 0.001) in the dyslipidemic group. ST-segment elevation myocardial infarction is standard in both groups. The maximum patient has regional wall motion abnormality in echocardiography after day 3 of admission. Among the dyslipidemic group, ejection fraction was on the lower side, and the predominant complication was in the left ventricular failure (LVF) (P < 0.05). Conclusion: WC has a positive association with patients with AMI who have dyslipidemia and can be used as an indicator of the risk of AMI when BMI is normal. WC is a surrogate marker of abdominal fat mass (subcutaneous and intra-abdominal); increased WC is a significant component marker of metabolic syndrome and insulin resistance related to cardiovascular mortality. There was poor glycemic control and blood pressure (mainly DBP) among the dyslipidemic patients. Hypertriglyceridemia is the most common lipid abnormality, followed by hypercholesterolemia among the dyslipidemic group. LVF is the most common complication in dyslipidemic patients.
