Current smokers have twice the risk of cardiovascular mortality compared with never smokers. Former smokers have about a 37% increased risk of cardiovascular mortality compared to never smokers. The excess risk in smokers was positively correlated with number of cigarettes smoked per day. The excess risk in former smokers decreased continuously with time since smoking cessation.

Prospective validation of a 1-hour algorithm to rule-out and rule-in acute myocardial infarction using a high-sensitivity cardiac troponin T assay
A rapid strategy to evaluate patient with suspected acute myocardial infarction included a baseline high sensitivity cardiac troponin T level, a repeat level in 1 hour, and observation care for equivocal cases. Within 1 hour, 40% of patients were classified as ruled-in or ruled-out, and 60% went on to observation care. The sensitivity and negative predictive value in the ruled-out group was over 99%. 30-day mortality was 0% in the ruled out group. (CMAJ 2015. DOI:10.1503 /cmaj.141349)Read More
