SuPAR predicts postoperative complications and mortality in patients with asymptomatic aortic stenosis.

Background: We evaluated whether early measurement of soluble urokinase plasminogen activator receptor (suPAR) could predict future risk of postoperative complications in initially asymptomatic patients with mild-moderate aortic stenosis (AS) undergoing aortic valve replacement (AVR) surgery. Methods: Baseline plasma suPAR levels were available in 411 patients who underwent AVR surgery during follow-up in the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) study. Cox analyses were used to evaluate suPAR in relation to all-cause mortality and the composite endpoint of postoperative complications (all-cause mortality, congestive heart failure, stroke and renal impairment) occurring in the 30-day postoperative period. Results: Patients with initially higher levels of suPAR were at increased risk of postoperative mortality with a HR of 3.5 (95% CI 1.4 to 9.0, P=0.008) and postoperative complications with a HR of 2.7 (95% CI 1.5 to 5.1, P=0.002), per doubling in suPAR. After adjusting for the European System for Cardiac Operative Risk Evaluation or Society of Thoracic Surgeons risk score, suPAR remained associated with postoperative mortality with a HR 3.2 (95% CI 1.2 to 8.6, P=0.025) and 2.7 (95% CI 1.0 to 7.8, P=0.061); and postoperative complications with a HR of 2.5 (95% CI 1.3 to 5.0, P=0.007) and 2.4 (95% CI 1.2 to 4.8, P=0.011), respectively. Conclusion: Higher baseline suPAR levels are associated with an increased risk for postoperative complications and mortality in patients with mild-moderate, asymptomatic AS undergoing later AVR surgery. Further validation in other subsets of AS individuals are warranted. Trial registration number: NCT00092677; Post-results.

Prognosis of acute coronary events is worse in patients living alone: the FINAMI myocardial infarction register.

BACKGROUND: Single living has been associated with a worse prognosis of acute coronary syndrome (ACS). We aimed to study the relation of sociodemographic characteristics to the morbidity, mortality, and case fatality (CF) of ACS in a large population-based ACS register. METHODS: The population-based FINAMI myocardial infarction register recorded 15,330 cases of ACS among persons aged 35-99 years in Finland in 1993-2002. Record linkage with the files of Statistics Finland provided information on sociodemographic characteristics (marital status, household size). RESULTS: ACS incidence and 28-day mortality rate were higher in unmarried men and women in all age groups. The prehospital CF of incident ACS was higher in single living and/or unmarried 35-64-year-old people. The 28-day CF was 26% (95% confidence interval, CI, 24-29%) in married men, 42% (95% CI 37-47%) in men who had previously been married, and 51% (95% CI 46-57%) in never-married men. Among women, the corresponding figures were 20% (95% CI 15-24%), 32% (95% CI 25-39%), and 43% (95% CI 31-56%). Most of these CF differences were apparent already at the prehospital phase. The only difference in treatment was that middle-aged men living alone or unmarried received thrombolysis less often. The disparities in ACS morbidity and mortality by marital status tended to widen during the study period. CONCLUSIONS: Single living and/or being unmarried increases the risk of having a heart attack and worsens its prognosis both in men and women regardless of age. Most of the excess mortality appears already before the hospital admission and seems not to be related to differences in treatment of ACS.

Socioeconomic inequalities in the morbidity and mortality of acute coronary events in Finland: 1988 to 2002.

PURPOSE: To examine the changes in socioeconomic disparities in the incidence of coronary heart disease (CHD) and mortality in Finland and to analyze the effects of the severe economic recession of the early 1990s on these disparities. METHODS: The population-based FINAMI Myocardial Infarction (MI) register recorded all suspected MI events among men and women ages 35 to 99 years in four geographical areas of Finland. Record linkage with the files of Statistics Finland provided us with detailed information on the indicators of socioeconomic status (SES; income, education, and profession). Rates were expressed per 100,000 inhabitants of each socioeconomic group per year and age-standardized to the European standard population. Poisson regression was used for analyzing rate ratios and time trends of coronary events in different socioeconomic groups. RESULTS: The mortality rate ratio of coronary events among 35- to 64 year-old men was 5.21 (95% confidence interval, 4.23-6.41) when the lowest income sixth to the highest income sixth were compared. Among women, the respective rate ratio was 11.13 (5.77-21.45). Significant differences in the incidence and 28-day mortality by SES were seen also in the older age groups. Some socioeconomic differences were found in the proportions of patients receiving thrombolysis or undergoing early revascularization. No substantial changes were observed in inequalities between the socioeconomic groups during the study period. CONCLUSIONS: The excess CHD morbidity and mortality among persons with lower SES is still considerable in Finland, but the economic recession did not widen the differences.
