Presentation and In-Hospital Outcome in First Attack of Acute Coronary Syndrome among Diabetic and Non-Diabetic People.
This was a prospective and observational study. One hundred and sixty five consecutive patients (75 diabetic and 90 were non-diabetic) admitted to coronary care unit in Rangpur Medical College and Hospital, Rangpur from December 2011 to June 2012 with the diagnosis of first attack of acute coronary syndrome were included in this study. Patients were selected considering the inclusion and exclusion criteria, Symptom time, typical or atypical chest pain, Dysponea, palpitation, cardiogenic shock, cardiac arrest, vital signs and Killip classes were regarded as presentation at admission. Outcome parameters observed during the hospital stay were in-hospital mortality, cardiogenic shock, congestive cardiac failure, symptomatic arrhythmias, cardiac arrest, recurrent ischemia and hospital stay. The results were obtained by calculating 'p' value by 'z' test, 't' test, chi-square test, as appropriate to see the difference between two groups. The results thus obtained were plotted on table, pie-chart, line chart, bar-diagram etc. as appropriate p value <0.05 was considered significant. In the study, diabetic patients presented with acute coronary syndrome at earlier age (p=053). Body Mass Index was significantly more in diabetic group (25.053 ± 2.1428 vs. 24.0822 kg/m² ± 2.233 kg/m², p=0.0045). Atypical chest pain (40% vs. 24.4%, p=0.0323), Dysponea (53.3 vs. 36.7%, p=0.0315), cardiac shock (17.33 vs. 6.7%, p=0.03236) and symptom duration before presentation (31.067 ± 42.5 hours vs. 19.44 ± 30.3 hours, p=0.0471) were significantly more observed in diabetic group. In respect of outcome, diabetic patients experienced more recurrent ischemia (24% vs. 16.67%, p=0.0524) and heart failure (36% vs. 22.2%, p=0.05). Hospital stay was also found significantly higher in diabetic group (5.097 ± 1.023 vs. 4.097 ± 1.009, p=0.0078). Atypically presented group suffered significantly more from congestive heart failure p=0.0392. Triglyceride level (230.7 ± 61.7 vs. 180.1 ± 39.1, p<0.001) were significantly more in diabetic group. The mean value of Hba1C in diabetic patients was 8.0278 ± 10.44965%. This study suggested that atypical chest pain, dysponea and cardiac shock were more in diabetic group at presentation. Recurrent ischemia, heart failure and hospital stay were more in diabetic group as outcome.
