Trends in cardiovascular risk factor and disease prevalence in patients undergoing non-cardiac surgery.

ABSTRACT: OBJECTIVES:Cardiovascular risk factors are prevalent in the population undergoing non-cardiac surgery. Changes in perioperative cardiovascular risk factor profiles over time are unknown. The objective of this study was to evaluate national trends in cardiovascular risk factors and atherosclerotic cardiovascular disease (ASCVD) among patients undergoing non-cardiac surgery. METHODS:Adults aged ?45 years old who underwent non-cardiac surgery were identified using the US National Inpatient Sample from 2004 to 2013. The prevalence of traditional cardiovascular risk factors (hypertension, dyslipidaemia, diabetes mellitus, obesity and chronic kidney disease) and ASCVD (coronary artery disease, peripheral artery disease and prior stroke] were evaluated over time. RESULTS:A total of 10 581 621 hospitalisations for major non-cardiac surgery were identified. Between 2008 and 2013, ?2?cardiovascular risk factors and ASCVD were present in 44.5% and 24.3% of cases, respectively. Over time, the prevalence of multiple (?2) cardiovascular risk factors increased from 40.5% in 2008-2009 to 48.2% in 2012-2013, P<0.001. The proportion of patients with coronary artery disease (17.2% in 2004-2005 vs 18.2% in 2012-2013, P<0.001), peripheral artery disease (6.3% in 2004-2005 vs 7.4% in 2012-2013, P<0.001) and prior stroke (3.5% in 2008-2009 vs 4.7% 2012-2013, P<0.001) also increased over time. The proportion of patients with a modified Revised Cardiac Risk Index score??3 increased from 6.6% in 2008-2009 to 7.7% in 2012-2013 (P<0.001). CONCLUSIONS:Among patients undergoing major non-cardiac surgery, the burden of cardiovascular risk factors and the prevalence of ASCVD increased over time. Adverse trends in risk profiles require continued attention to improve perioperative cardiovascular outcomes.

Project description:BACKGROUND:It is unclear if isolated postoperative cardiac-troponin elevation, often referred to as myocardial injury, represents a pathological event, as control studies in otherwise healthy adults are lacking. METHODS:In this single-centre prospective observational cohort study, serial high-sensitivity cardiac troponin T (hscTnT) plasma concentrations were obtained from young, healthy adults undergoing elective orthopaedic surgery at three time points: before operation, 2-6 h, and 18-30 h after surgery. End points were hscTnT increases after surgery: ?20% (exceeding analytical variability), ?50% (exceeding short-term biological variability), and ?85% (exceeding long-term biological variability). The secondary end point was myocardial injury, defined as new postoperative hscTnT elevation >99th % upper reference limit (URL) (women >10 ng litre-1; men >15 ng litre-1). RESULTS:Amongst the study population (n=95), no hscTnT increase ?20% was detected in 68 patients (73%). A hscTnT increase between 20% and 49% was observed in 17 patients (18%), 50-84% in seven patients (7%), and ?85% in three patients (3%). Twenty patients (21%) had an absolute ?hscTnT between 0 and 2 ng litre-1, 12 patients (13%) between 2 and 4 ng litre-1, three patients between 4 and 6 ng litre-1, and one patient (1%) between 6 and 8 ng litre-1. Myocardial injury (new hscTnT elevation >99th%) was diagnosed in one patient (1%). The median hscTnT concentrations did not increase after operation, and were 4 (3.9-5, inter-quartile range) ng litre-1 at baseline, 4 (3.9-5) ng litre-1 at 2-6 h after surgery, and 4 (3.9-5) ng litre-1 on postoperative day 1. CONCLUSIONS:One in four young adult patients without known cardiovascular disease developed a postoperative hscTnT increase, but without exceeding the 99th% URL and without evidence of myocardial ischaemia. These results may have important ramifications for the concept of postoperative myocardial injury, as they suggest that, in some patients, postoperative cardiac-troponin increases may be the result of a normal physiological process in the surgical setting.
