Objective: Cardiovascular disease is the leading cause of death among Indian adults, and approximately 50% of deaths usually occur during the 1st hour after symptom onset before arriving at the hospital. A study was planned to evaluate the prehospital and hospital delay in patients with acute myocardial infarction (AMI). Methods: This was a prospective observational study of 390 patients with AMI admitted to the Department of Cardiology between March 2014 and August 2015. Detailed patient demographics, socioeconomic status, and prehospital and hospital delay were reviewed. Results: The mean age of presentation for male and female was 57 ± 12.91 and 61.5 ± 12.83 years, respectively. The mean prehospital delay, time to act after chest pain, and travel time were 9.08 ± 6.3, 7.16 ± 6.1, and 1.84 ± 0.8 h, respectively, and only three (9.7%) patients reached the hospital within 2 h after symptom onset. Out of 300 patients who received reperfusion therapy, thrombolysis was done in 276 (92%) patients while primary percutaneous coronary intervention was performed in only 24 (8%) patients. Mean door-to-needle (D-N) time and door-to-device time for those who received reperfusion therapy were 27.8 ± 4.3 and 78.95 ± 9.5 min, respectively. A multivariate logistic regression analysis revealed that the prehospital delay was significantly associated with older age, female sex, rural background, diabetes, having atypical pain, and lack of knowledge regarding the seriousness of chest pain. Conclusion: Approximately 79% of total prehospital delay was due to patient-related factors; old age, female sex, rural background, diabetes, atypical angina, and lack of knowledge being the significant attributes. D-N time and door-to-device time were within the limits of those recommended by current guidelines.
