Risk factors for acute coronary syndrome in patients below the age of 40 years

Background

Acute coronary syndrome (ACS) refers to a spectrum of symptoms compatible with acute myocardial ischemia. Plasma markers of inflammation have been recently identified as diagnostic aid and risk predictors. The present study, conducted in Slemani Cardiac Hospital (SCH), Sulaimaniyah, Iraq aimed to recognize some risk factors for ACS in Iraqi adults younger than 40.

Methodology

This is a prospective case-control study of 100 patients with ACS vs. a control group of 100 healthy volunteers. The study began at 1st January 2014 and ended at 31st December 2016. All patients were subjected to full history taking, clinical examination including measurement of waist circumference and body mass index (BMI). Investigations included electrocardiography (ECG), echocardiography, full blood count, measurement of lipid profile and C-reactive protein (CRP). The patients were managed by percutaneous coronary intervention (PCI).

Results

The mean age of the patients was 36?years (range 28–40). Eighty-five% of patients were male. The mean BMI (29?kg/m²) and waist circumference (98?cm) of the patients were higher than the controls (24?kg/m² and 72?cm respectively). The leukocytes, lymphocytes and neutrophil counts as well as CRP in both groups were within the normal range. The most prevalent risk factor was obesity (n?=?86). Other risk factors were smoking (n?=?62), hypertension (n?=?26), diabetes mellitus (n?=?22) and positive family history of ACS (n?=?24). Most patients (n?=?83) had multi-vessel coronary artery disease (2–3 vessels).

Conclusion

ACS in young adults is an increasing health problem. Obesity was found to be the most prevalent risk factor.
