Prehospital delay in patients hospitalized with acute myocardial infarction in the emergency unit of a North Indian tertiary care hospital.

BACKGROUND: Prompt treatment of patients presenting with acute myocardial infarction decreases the incidence of death from early arrhythmia, and maximizes the potential benefit of thrombolytic therapy. Prehospital delay has been identified as a major obstacle to the widespread use of thrombolytic therapy. The aim of the present study was to examine the extent of, and factors associated with, delay in seeking medical care (usually thrombolytic therapy) in patients with acute myocardial infarction. METHODS AND RESULTS: The study was conducted in patients visiting the medical emergency unit of the Nehru Hospital, Post Graduate Institute of Medical Education and Research, Chandigarh. A total of 104 patients diagnosed with acute myocardial infarction were interviewed using a pre-designed proforma. Pain-to-door, and door-to-drug times, were the main outcome measures. The corrected mean (SEM) and median (range) pain-to-door times were 8.5 (0.8) hours and 5.2 (0.5-24) hours, respectively. Out of 104 patients, 38 did not receive thrombolytic therapy. In those who did not receive thrombolytic therapy, prior therapy at local health centers, lack of knowledge of symptoms, and transportation problems were the main reasons for hospital delay. The mean (SEM) and median (range) of door-to-drug times were 1.2 (0.1) hours and 1 (0.2-3.5) hours, respectively.

Role of foetal echocardiography in predicting perinatal outcome.

To establish foetal cardiovascular parameters as predictors of perinatal outcome in pregnancy, M-Mode, 2-D echocardiography and pulse Doppler study was performed at 24-32 weeks of gestation in 65 pregnancies. These pregnancies were followed up for perinatal outcome. The studied population included 24 normal pregnancies, 21 pregnant women with heart disease (14 rheumatic and 7 congenital heart disease) and 20 high risk pregnancies (bad obstetric history in 7, suspected intrauterine growth retardation in 4, hypertensive disease of pregnancy in 6 and diabetes mellitus in 3). There was no perinatal mortality. Two foetuses were born with complete heart block and one with a small ventricular septal defect; 6 neonates had intrauterine growth retardation and two of these had neonatal asphyxia with APGAR score less than 6 at one minute. Anatomically normal heart was correctly diagnosed in all 64 foetuses and ventricular septal defect was detected antenatally in one. Antenatal diagnosis of complete heart block was correctly made in two foetuses. One new born with complete heart block required a permanent pacemaker, which was implanted. The ratio of peak velocity across mitral valve during atrial systole (A) to peak velocity during early diastolic ventricular filling (E) was chosen to correlate with perinatal outcome. The ratio was less than 1.0 in 6 foetuses, all of whom were subsequently confirmed to have intrauterine growth retardation. In normal pregnancies A/E ratio was more than 1.0. We conclude that foetal echocardiography is a useful tool for predicting perinatal outcome and may be helpful in screening patients who require specific perinatal management.
