Abstract

Background: Cardiogenic shock (CS) is a serious and potentially fatal complication of acute coronary syndromes, including non-ST-elevation myocardial infarction (NSTEMI). Identifying its frequency and associated risk factors is essential for prompt risk stratification and management. Objective: To determine the frequency of cardiogenic shock in adult patients presenting with NSTEMI. Study Design: Cross-sectional. Setting: Department of Cardiology, Lady Reading Hospital, Peshawar, Pakistan. Duration of Study: From November 8, 2024, to May 8, 2025. Methods: A total of 146 patients aged 30 to 70 years diagnosed with NSTEMI were enrolled consecutively. Cardiogenic shock was defined as a systolic blood pressure <90 mmHg for ≥30 minutes, a cardiac index <1.8 L/min/m², or pulmonary capillary wedge pressure >18 mmHg. Clinical variables, including diabetes, hypertension, and smoking status, were recorded. Data were analyzed using appropriate statistical methods to determine associations (p<0.05 considered significant). Results: The mean age of the study population was 57.91 ± 10.38 years. Among the patients, 92 (63.0%) were male and 54 (37.0%) were female. Cardiogenic shock was diagnosed in 9 patients (6.2%). A statistically significant association was found between cardiogenic shock and diabetes (p=0.04), hypertension (p=0.009), and smoking (p=0.0001). Conclusion: Cardiogenic shock occurred in 6.2% of patients with NSTEMI in this study. Diabetes, hypertension, and smoking were significantly associated with the development of cardiogenic shock, underscoring the need for careful monitoring and early intervention in high-risk individuals.
