Comparison of characteristics and outcomes of percutaneous coronary intervention in military and non-military men

Objectives

Living in a military environment, as a unique job and lifestyle, may affect the physical and mental status of military personnel. Coronary artery disease (CAD) status and outcomes of percutaneous coronary intervention (PCI) in military personnel as a unique part of each society are less investigated.

Method

In a registry-based study, data of 338 military men and 1954 non-military men who underwent successful PCI from March 2012 to March 2013 were analysed. The primary endpoint was major adverse cardiac events (MACE) after hospital discharge during 1-year follow-up.

Results

Military men were significantly younger and had a higher frequency of hypertension, familial history of CAD and cigarette smoking. Other risk factors were more prevalent in non-military men. PCI for ST-segment elevation myocardial infarction and lower left ventricular ejection fraction were also more prevalent in soldiers. After mean follow-up duration of 12.3 months, MACE that was defined as the composite endpoint of all-cause mortality, non-fatal myocardial infarction or target vessel revascularisation was similar in both groups (HR=1.01 (95% CI 0.88 to 1.16); p=0.872). By adjustment for confounding factors, results were unchanged.

Conclusions

Although there are a number of differences in basic and procedural characteristics between military and non-military men who underwent PCI, 1-year clinical outcomes of this procedure are not different in these patient groups.
