Abstract
The prevalence of acute myocardial infarction in younger than 45 years was higher than expected before in recent studies, and the echocardiography was an important for evaluation of EF, WMSI, and complications. This study was done to evaluate its incidence and clinical characteristics in Egypt.
Aim:
To explore prevalence the clinical and echo characteristics in patients with MI aged below 45 years as compared to those aged 45 years or more .
Patients and methods:
- The study included one hundred and fifty three patients with first time acute myocardial infarction. They were divided into two groups. Group I included patients less than 45 years, and groupII was those older than 45 years.
- All patients underwent 12 lead ECG, echocardiography to measure EF, WMSI and laboraotry investigations for:
- Fasting blood sugar, CPK-MB, and cholesterol.
- Patients underwent psychiatric analysis for anxiety by using Taylor scale and depression analysis by using Beck scale.
Results:
- Incidence of the first time acute myocardial infarction in young group was (14%). With predominance of males, its incidence was (86.4%). The ratio of male to female was 6.3:1.
- Tobacco smoking incidence in group I was (86.4%) while cannabis incidence was (18.4%) which were important risk factors for young age.
- Diabetes and HTN were predominant risk factors in groupII, the incidence of diabetes was (53.4%) and the incidence of HTN was (48.09%).
- There was no significant difference in both groups as regards to anginal pain, it was (86.4%) in group I and (92.4%) in group II.
- There was non significant difference in both groups regarding to the treatment whether thrombolytic therapy or PCI (88.4%vs91.1%&and 5.5%vs 8.8%) respectively.
- Laboratory showed non significant difference in both groups regarding to CBK, MB, and serum cholestrol. While there was significant difference as regards to fasting blood sugar, it was higher in group II than group I (175.17 +85.6 vs 134.25+60.6.
- Anxiety was an important risk factor in groupI, its incidence was (68.2%) versus ( 21.37%) in group II .
- Anterior STEMI was more predominant in both groups, its incidence was (61%) in group I, and (70%) in group II.
- Ejection fraction was lower in group II than in group I. its mean in group I was 54+13.01wherase its mean in group II was 44.69+10.34.
- In conclusion: the incidence of acute myocardial infarction in younger group was 14.4% of all patients .Smoking and anxiety were predominant risk factors in younger group.Ejection fraction was better than older age group.While hypertension ,diabetes mellitus were more common in group II.
