ABSTRACT: AIMS: We examined whether severity of coronary artery disease (CAD) measured by coronary computed tomography angiography can be used to predict rates of myocardial infarction (MI) and death in patients with and without diabetes. METHODS AND RESULTS: A cohort study of consecutive patients (n = 48 731) registered in the Western Denmark Cardiac Computed Tomography Registry from 2008 to 2016. Patients were stratified by diabetes status and CAD severity (no, non-obstructive, or obstructive). Endpoints were MI and death. Event rates per 1000 person-years, unadjusted and adjusted incidence rate ratios were computed. Median follow-up was 3.6 years. Among non-diabetes patients, MI event rates per 1000 person-years were 1.4 for no CAD, 4.1 for non-obstructive CAD, and 9.1 for obstructive CAD. Among diabetes patients, the corresponding rates were 2.1 for no CAD, 4.8 for non-obstructive CAD, and 12.6 for obstructive CAD. Non-diabetes and diabetes patients without CAD had similar low rates of MI [adjusted incidence rate ratio 1.40, 95% confidence interval (CI): 0.71-2.78]. Among diabetes patients, the adjusted risk of MI increased with severity of CAD (no CAD: reference; non-obstructive CAD: adjusted incidence rate ratio 1.71, 95% CI: 0.79-3.68; obstructive CAD: adjusted incidence rate ratio 4.42, 95% CI: 2.14-9.17). Diabetes patients had higher death rates than non-diabetes patients, irrespective of CAD severity. CONCLUSION: In patients without CAD, diabetes patients have a low risk of MI similar to non-diabetes patients. Further, MI rates increase with CAD severity in both diabetes and non-diabetes patients; with diabetes patients with obstructive CAD having the highest risk of MI.

3 Article Neither long-term statin use nor atherosclerotic disease is associated with risk of colorectal cancer. 2010

Robertson, Douglas J / Riis, Anders Hammerich / Friis, Søren / Pedersen, Lars / Baron, John A / Sørensen, Henrik Toft. ·VA Medical Center, White River Junction, Vermont 05009, USA. douglas.robertson@va.gov ·Clin Gastroenterol Hepatol · Pubmed #20816860.

ABSTRACT: BACKGROUND & AIMS: Statin use has been reported to reduce risk for colorectal cancer (CRC) whereas atherosclerotic disease has been reported to increase risk, but findings have been inconsistent. We aimed to establish the association of statin use and coronary atherosclerosis with CRC. METHODS: We performed a population-based case control study of patients with a first diagnosis of CRC cancer between January 1, 1991, and December 31, 2008 (n = 9979), using the Danish National Registry of Patients. As many as 10 population controls were matched to each patient using risk set sampling (n = 99,790). Statin use before cancer diagnosis (or control index date) was determined via county prescription databases and evidence of coronary atherosclerosis using International Classification of Diseases codes. We calculated incidence rate ratios using conditional logistic regression, adjusted for multiple covariates. RESULTS: Among patients with CRC, statin use was modest (7.7%), but 23.5% of use was long term (≥5 years). Ever use of statins (≥2 prescriptions) slightly reduced CRC risk, compared with relative to never/rare use (incidence rate ratio [IRR] = 0.87, 95% confidence interval = 0.80-0.96). However, long-term use did not affect risk compared with never/rare use (IRR = 0.95, 95% 0.80-1.12). No associations were observed between atherosclerosis, myocardial infarction, or stroke, and CRC incidence. CONCLUSIONS: Although there is a weak inverse association between ever use of statins and CRC incidence, there was no trend with increasing duration of use, so statins do not appear to reduce CRC risk. We did not confirm the reported association between atherosclerosis and CRC risk.
