    • OBJECTIVE: Women with severe aortic valve stenosis (AS) have better LV systolic function and more concentric LV geometry than their male counterparts. However, sex differences in cardiovascular (CV) outcome during progression of AS have not been reported from a longitudinal prospective study.METHODS: Doppler echocardiography and CV events were recorded during a median of 4.0 years in 979 men and 632 women aged 28-86 (mean 67±10) years in the Simvastatin Ezetimibe in Aortic Stenosis (SEAS) study. LV systolic function was assessed by EF and midwall shortening (MWS). Study outcomes were AS-related events, ischaemic CV events and total mortality.RESULTS: The annular cumulative incidence of AS events, ischaemic CV events and death was 8.1%, 3.4% and 2.8% in women, and 8.9%, 4.4% and 2.4% in men, respectively. Women and men had similar AS progression rate whether measured by peak jet velocity, mean gradient or valve area. In multivariate analyses, female sex independently predicted less reduction in LV MWS and EF during follow-up (both p<0.05). In time-varying Cox analyses, women had a 40% lower rate of ischaemic CV events (95% CI 21% to 54%), in particular, more than 50% lower rate of stroke and coronary artery bypass grafting, and a 31% lower all-cause mortality (95% CI 1% to 51%), independent of active study treatment, age and hypertension, as well as time-varying valve area, low systolic function and abnormal LV geometry. AS event rate did not differ by sex.CONCLUSIONS: In the SEAS study, women and men had similar rates of AS progression and AS-related events. However, women had lower total mortality and ischaemic CV event rate than men independent of confounders.TRIAL REGISTRATION NUMBER: ClinicalTrials.gov identifier: NCT00092677.

    • Asymmetric interventricular septum hypertrophy (ASH) has been associated with increased perioperative morbidity and mortality in patients with severe, symptomatic aortic valve stenosis (AS). Less is known about the prognostic impact of ASH during progression of AS. Clinical, echocardiographic, and outcome data from 1,691 patients with initially asymptomatic, mostly moderate AS, participating in the Simvastatin Ezetimibe in Aortic Stenosis (SEAS) study was used. ASH was considered present if interventricular septum/posterior wall thickness ratio in end-diastole ≥1.5. The associations of ASH with hazard rate of ischemic cardiovascular events were tested in time-dependent Cox regression analyses. Based on the presence of ASH at study echocardiograms, the study population was grouped in to a no-ASH, nonpersistent ASH, persistent ASH, and new-onset ASH groups. During a median of 4.3 years of follow-up, ASH persisted or developed in 17% of patients. Persistent or new-onset ASH was characterized by higher left ventricular mass index and ejection fraction at baseline (both p <0.05) but not with female gender or hypertension. In time-varying Cox regression analyses adjusting for these confounders, persistent or new-onset ASH was associated with higher hazard rate of ischemic cardiovascular events (hazard rate 1.45; 95% confidence interval 1.09 to 1.91, p = 0.01), in particular coronary artery bypass grafting (hazard rate 1.69; 95% confidence interval 1.17 to 2.47; p = 0.006), whereas no association with increased mortality was found. In conclusion, in patients with AS without diabetes or known renal or cardiovascular disease participating in the SEAS study, persistent or new-onset ASH during progression of AS was associated with higher rate of ischemic cardiovascular events.

  • Gender differences in left ventricular structure and function during antihypertensive treatment : the Losartan intervention for endpoint reduction in hypertension study

    • In hypertensive patients with left ventricular hypertrophy, antihypertensive treatment induces changes in left ventricular structure and function. However, less is known about gender differences in this response. Baseline and annual echocardiograms until the end of study or a primary end point occurred were assessed in 863 hypertensive patients with electrocardiographic left ventricular hypertrophy aged 55 to 80 years (mean: 66 years) during 4.8 years of randomized losartan- or atenolol-based treatment in the Losartan Intervention for Endpoint Reduction in Hypertension Echocardiography substudy. Left ventricular hypertrophy was diagnosed as left ventricular mass divided by height(2.7) >or=46.7 g/m(2.7) and 49.2 g/m(2.7) in women and men, respectively, and systolic function as ejection fraction and stress-corrected midwall fractional shortening. Women included more patients with obesity, isolated systolic hypertension, and mitral regurgitation (all P<0.01). Ejection fraction, stress-corrected midwall shortening, and prevalence of left ventricular hypertrophy were higher in women at baseline and at the end of study (all P<0.01). In particular, more women had residual eccentric hypertrophy (47% versus 32%; P<0.01) in spite of similar in-treatment reduction in mean blood pressure. In logistic regression, left ventricular hypertrophy at study end was more common in women (odds ratio: 1.61; 95% CI: 1.16 to 2.26; P<0.01) independent of other significant covariates. In linear regression analyses, female gender also predicted 2% higher mean in-treatment ejection fraction and 2% higher mean stress-corrected midwall shortening (both beta=0.07; P<0.01). Hypertensive women in this study retained higher left ventricular ejection fraction and stress-corrected midwall shortening in spite of less hypertrophy regression during long-term antihypertensive treatment.

  • Usefulness of the electrocardiogram in predicting cardiovascular mortality in asymptomatic adults with aortic stenosis (from the Simvastatin and Ezetimibe in Aortic Stenosis study)
  • 2014
  • Ingår i: American Journal of Cardiology. - : Elsevier. - 0002-9149 .- 1879-1913. ; 114:5, s. 751-756

    • Hypertension and coronary heart disease are common in aortic stenosis (AS) and may impair prognosis for similar AS severity. Different changes in the electrocardiogram may be reflective of the separate impacts of AS, hypertension, and coronary heart disease, which could lead to enhanced risk stratification in AS. The aim of this study was therefore to examine if combining prognostically relevant electrocardiographic (ECG) findings improves prediction of cardiovascular mortality in asymptomatic AS. All patients with baseline electrocardiograms in the SEAS study were included. The primary end point was cardiovascular death. Backward elimination (p > 0.01) identified heart rate, Q waves, and Cornell voltage-duration product as independently associated with cardiovascular death. Multivariate logistic and Cox regression models were used to evaluate if these 3 ECG variables improved prediction of cardiovascular death. In 1,473 patients followed for a mean of 4.3 years (6,362 patient-years of follow-up), 70 cardiovascular deaths (5%) occurred. In multivariate analysis, heart rate (hazard ratio [FIR] 1.5 per 11.2 minute(-1) [1 SD], 95% confidence interval [CI] 1.2 to 1.8), sum of Q-wave amplitude (HR 1.3 per 2.0 nun [1 SD], 95% CI 1.1 to 1.6), and Cornell voltage-duration product (FIR 1.4 per 763 mm x ms [1 SD], 95% CI 1.2 to 1.7) remained independently associated with cardiovascular death. Combining the prognostic information contained in each of the 3 ECG variables improved integrated discrimination for prediction of cardiovascular death by 2.5%, net reclassification by 14.3%, and area under the curve by 0.06 (all p <= 0.04) beyond other important risk factors. ECG findings add incremental predictive information for cardiovascular mortality in asymptomatic patients with AS.

  • Effect of Overweight and Obesity on Cardiovascular Events in Asymptomatic Aortic Stenosis
  • 2013
  • Ingår i: Journal of the American College of Cardiology. - : Elsevier. - 0735-1097 .- 1558-3597. ; 62:18, s. 1683-1690

    • Objectives This study investigated whether overweight and obesity impacted outcome in patients with aortic valve stenosis (AS). Background Increased body mass index (BMI) is a strong predictor of higher cardiovascular (CV) morbidity and mortality in the general population but not among patients undergoing heart surgery. Methods Cardiovascular events in 1,664 patients with initially asymptomatic AS were recorded during a mean of 4.3 years of follow-up in the SEAS (Simvastatin Ezetimibe in Aortic Stenosis) study. Patients were grouped according to baseline BMI class. Results Overweight (n = 737) and obese patients (n = 334) had higher prevalence of hypertension, more abnormal left ventricular geometry, and lower stress-corrected midwall shortening throughout the study compared with normal weight patients (all p < 0.01). The AS progression rate did not differ between BMI classes. In univariate Cox regression, overweight was associated with a 17% to 22% lower rate of AS-related (p = 0.04) and ischemic CV events (p = 0.05). In multivariate analyses, adjusting for AS severity and differences in baseline characteristics, overweight had no significant influence on the rate of ischemic CV or AS-related events, whereas overweight and obesity had 46% and 67% higher rate of total mortality and 42% and 69% higher rate of combined hospital stay for heart failure and death from any cause, respectively, compared with normal weight patients (all p < 0.05). Conclusions In patients with initially asymptomatic AS participating in the SEAS study, overweight and obesity did not influence AS progression or rate of AS-related or ischemic CV events but were both associated with increased mortality.
