Dipstick proteinuria and risk of myocardial infarction and all-cause mortality in diabetes or pre-diabetes: a population-based cohort study.

ABSTRACT: To evaluate the association between dipstick proteinuria and myocardial infarction (MI) or all-cause mortality, a cohort study was conducted among 16,573 general Chinese population with diabetes or pre-diabetes, which were defined as self-reported history of diabetes or fasting blood glucose ?5.6?mmol/L or under blood glucose lowering therapy. Proteinuria was detected biennially during 2006-2013 by dipstick test. MI and all-cause mortality were recorded through the end of 2014. Mean age (standard deviation) of study participants was 51.16 (10.63) years, with 82.24% of male. During a median follow-up of 8.03 years, 211 MI and 403 all-cause mortality occurred. Multivariable Cox regression revealed occasional or persistent detection of trace or higher in proteinuria increased the risk of all-cause mortality, with hazard ratios (HRs) of 1.42 (95% confidence intervals [CI]: 1.10, 1.83) and 2.23 (95% CI: 1.66, 3.01), respectively, compared to sustained negative in proteinuria. A time-dependent analysis also revealed the association between degree of proteinuria and all-cause mortality, with HRs of 1.80 (95% CI: 1.31, 2.48) for trace and 3.34 (95% CI: 2.40, 4.65) for one plus or higher in proteinuria, compared to negative. The associations regarding MI lost statistical significance after multivariable adjustment. In conclusion, dipstick proteinuria was associated with an increased risk of MI and all-cause mortality among a general population with diabetes or pre-diabetes.

Project description:BackgroundSurvivors of acute myocardial infarction (AMI) are at increased risk of dying within several hours to days following exposure to elevated levels of ambient air pollution. Little is known, however, about the influence of long-term (months to years) air pollution exposure on survival after AMI.ObjectiveWe conducted a population-based cohort study to determine the impact of long-term exposure to fine particulate matter ? 2.5 ?m in diameter (PM2.5) on post-AMI survival.MethodsWe assembled a cohort of 8,873 AMI patients who were admitted to 1 of 86 hospital corporations across Ontario, Canada in 1999-2001. Mortality follow-up for this cohort extended through 2011. Cumulative time-weighted exposures to PM2.5 were derived from satellite observations based on participants' annual residences during follow-up. We used standard and multilevel spatial random-effects Cox proportional hazards models and adjusted for potential confounders.ResultsBetween 1999 and 2011, we identified 4,016 nonaccidental deaths, of which 2,147 were from any cardiovascular disease, 1,650 from ischemic heart disease, and 675 from AMI. For each 10-?g/m3 increase in PM2.5, the adjusted hazard ratio (HR10) of nonaccidental mortality was 1.22 [95% confidence interval (CI): 1.03, 1.45]. The association with PM2.5 was robust to sensitivity analyses and appeared stronger for cardiovascular-related mortality: ischemic heart (HR10 = 1.43; 95% CI: 1.12, 1.83) and AMI (HR10 = 1.64; 95% CI: 1.13, 2.40). We estimated that 12.4% of nonaccidental deaths (or 497 deaths) could have been averted if the lowest measured concentration in an urban area (4 ?g/m3) had been achieved at all locations over the course of the study.ConclusionsLong-term air pollution exposure adversely affects the survival of AMI patients.CitationChen H, Burnett RT, Copes R, Kwong JC, Villeneuve PJ, Goldberg MS, Brook RD, van Donkelaar A, Jerrett M, Martin RV, Brook JR, Kopp A, Tu JV. 2016.
