Young patients undergoing percutaneous coronary intervention had a significantly lower risk of all-cause mortality at discharge compared to older patients (RR 0.49).

Do young patients undergoing PCI have different risk factor profiles and clinical outcomes compared to older patients?
Young patients undergoing PCI in Malaysia have a higher prevalence of smoking and obesity, a preponderance of single-vessel disease, and lower all-cause mortality at discharge compared to older patients.
Effect estimate: RR 0.49 (95% CI 0.26-0.94)
Absolute Event Rate: 0.7% vs 1.2%
BACKGROUND AND OBJECTIVES: Understanding the nature and pattern of young coronary artery disease (CAD) is important due to the tremendous impact on these patients' socio-economic and physical aspect. Data on young CAD in the southeast Asian region is rather patchy and limited. Hence we utilized our National Cardiovascular Disease Database (NCVD)-Percutaneous Coronary Intervention (PCI) Registry to analyze young patients who underwent PCI in the year 2007 to 2009. DESIGN AND SETTINGS: This is a retrospective study of all patients who had undergone coronary angioplasty from 2007 to 2009 in 11 hospitals across Malaysia. METHODS: Data were obtained from the NCVD-PCI Registry, 2007 to 2009. Patients were categorized into 2 groups-young and old, where young was defined as less than 45 years for men and less than 55 years for women and old was defined as more than or equals to 45 years for men and more than or equals to 55 years for women. Patients' baseline characteristics, risk factor profile, extent of coronary disease and outcome on dis.charge, and 30-day and 1-year follow-up were compared between the 2 groups. RESULTS: We analyzed 10268 patients, and the prevalence of young CAD was 16% (1595 patients). There was a significantly low prevalence of Chinese patients compared to other major ethnic groups. Active smoking (30.2% vs 17.7%) and obesity (20.9% vs 17.3%) were the 2 risk factors more associated with young CAD. There is a preponderance toward single vessel disease in the young CAD group, and they had a favorable clinical outcome in terms of all-cause mortality at discharge (RR 0.49 CI 0.26-0.94) and 1-year follow-up (RR 0.47 CI 0.19-1.15). CONCLUSION: We observed distinctive features of young CAD that would serve as a framework in the primary and secondary prevention of the early onset CAD.
Zuhdi et al. (Fri,) conducted a cohort in Coronary artery disease undergoing percutaneous coronary intervention (n=10,268). Young age (<45 years for men, <55 years for women) vs. Older age (≥45 years for men, ≥55 years for women) was evaluated on All-cause mortality at discharge (RR 0.49, 95% CI 0.26-0.94). Young patients undergoing percutaneous coronary intervention had a significantly lower risk of all-cause mortality at discharge compared to older patients (RR 0.49).
