Abstract

Background

The effect of income status on patient outcome merits investigation during periods of financial crisis. We evaluated the impact of income status on out-of-hospital prognosis in a cohort of acute coronary syndrome (ACS) patients, included in a countrywide study during a period of financial crisis.

Methods

The study is a secondary analysis of a prospective, multicenter, observational study–the PHAETHON study—enrolling consecutive ACS patients in 37 hospitals in Greece. Patients were classified as low or high income based on the reported net annual household income using as a cut-off point the relative poverty threshold for Greece of 12,000 Euros. The outcome measure was survival free of the primary composite endpoint (cardiovascular death, myocardial infarction, stroke/transient ischemic attack, urgent revascularization and urgent hospitalization due to cardiovascular causes).

Results

The study population included 794 patients. The administration rate of evidence-based medications was similar in the low- (n = 455) and high-income (n = 339) groups during hospitalization and upon discharge. In a median follow-up of 189 days (interquartile range: 180–212 days), low-income patients had 92 % higher risk of the combined endpoint as compared to high-income patients [Hazard ratio (HR):1.92, 95 % CI:1.25–2.94, p = 0.003]. The effect of low-income status on the combined outcome remained significant after adjustment for age, gender and depression (HR:1.59, 95 % CI:1.02–2.49; p = 0.043).

Conclusions

In a period of financial crisis, low income is a significant and independent predictor of poor out-of-hospital outcome in ACS patients. This association has profound implications and should be taken into consideration by public health policy makers.
