RT Journal Article SR Electronic T1 Trends in cardiovascular risk factor and disease prevalence in patients undergoing non-cardiac surgery JF Heart JO Heart FD BMJ Publishing Group Ltd and British Cardiovascular Society SP 1180 OP 1186 DO 10.1136/heartjnl-2017-312391 VO 104 IS 14 A1 Smilowitz, Nathaniel R A1 Gupta, Navdeep A1 Guo, Yu A1 Beckman, Joshua A A1 Bangalore, Sripal A1 Berger, Jeffrey S YR 2018 UL http://heart.bmj.com/content/104/14/1180.abstract AB 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.
