Major Bleeding Events Are Stronger Predictors of Long-Term Mortality Than Coronary Events in Secondary Prevention Therapy for Ischaemic Heart Disease.

ABSTRACT:

Background

Secondary prevention of ischaemic heart disease (IHD) is an important aspect of healthcare. To improve the prognosis of and control risk factors for IHD patients, we created a unique referral system called the Shizuoka IHD patient registry.

Methods

From 2009 to 2013, we enrolled 1240 patients; they participated in follow-up until 2018. The risk factor target values were as follows: low-density-lipoprotein cholesterol, <100?mg/dl; glycated haemoglobin of diabetes patients, <7%; systolic blood pressure, <130?mmHg; and diastolic blood pressure, <80?mmHg (mean follow-up interval, 2001?±?794 days). The cumulative incidence rates were 10.8% for all-cause death (cardiac death, 1.5%), 15.7% for coronary events, and 2.6% for major bleeding. Patients were separated into the major bleeding group (n?=?32), coronary event group (n?=?195), and event-free group (n?=?1013) without overlapping.

Results

We observed significant differences in age, rate antithrombotic drug use, and mortality. A Kaplan-Meier analysis of all-cause death showed significant differences between the event-free and major bleeding groups (P=0.002) and between the coronary event and major bleeding groups (P=0.026); there was no significant difference between the event-free and coronary event groups.

Conclusion

Major bleeding events were stronger predictors of long-term mortality than coronary events during the long-term follow-up of stable IHD.
