Asymptomatic Patients

Preoperative examination of patients undergoing high-risk elective non-cardiac surgery requires identifying factors associated with both the type of surgery and comorbidity profile of each patient. Determination of clinically significant echocardiographic changes, even without severe symptoms, can contribute to a change in management or revision of scheduled date and surgery tactics. The aspects of defining echocardiographic criteria for potential postoperative cardiovascular complications, especially in asymptomatic patients with preserved left ventricular ejection fraction, are an important clinical problem. The diastolic stress test, a relatively new type of exercise testing, is currently an additional diagnostic tool to detect heart failure in patients without reduced ejection fraction. The prospects of using this method before non-cardiac surgery in patients with preserved left ventricular ejection fraction is discussed in this article.

Abstract Background: Body mass index (BMI), age, left atrium (LA) dimensions and left ventricular ejection fraction (LVEF) have been linked to post-operative atrial fibrillation (POAF) after cardiac surgery. The aim was to better define the role of these risk factors. Methods: This study evaluated 249 patients (without prior atrial dysrhythmia) undergoing cardiac or aortic surgery . Prior to surgery the following data were collected: age (yrs), BMI (kg/m2), LA diameter (cm), LA area (cm2), LVEF (%), the presence of arterial hypertension (AH) and of diabetes, tyroid stimulating hormone (TSH, mU/L) and, creatinine (mg/dL). Results: Patients with (n. 127, 51%) and without POAF (n. 122, 49%) were compared. No difference was observed for sex, LA diameter, LA area, LVEF, TSH and diabetes. Instead, patients with PoAF had higher values of age, BMI, creatinine and a greater prevalence of AH and Bentall procedures. Multivariable analysis showed that the only independent predictors of PoAF were: age (OR = 1,05, CI 95% 1,025-1,076, p= 0,0001) and BMI (OR=1,095, CI 95% 1,015-1,182, p= 0,019). Conclusions: Results suggest that advanced age and a higher value of BMI are strong risk factors for POAF in patients without previous AF. This even in the presence of comparable LA dimensions and LVEF.
