- 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.

- BACKGROUND Fibro-calcification of the mitral annulus (MAC) has been associated with increased risk of ischemic stroke in general populations. This study was performed to assess whether MAC predicts incidence of ischemic stroke in treated hypertensive patients with left ventricular hypertrophy (LVH).METHODS Baseline and follow-up clinical and echocardiographic parameters were assessed in 939 hypertensive patients with electrocardiogram (ECG) LVH participating in the Losartan Intervention for Endpoint reduction in hypertension (LIFE) echocardiography substudy (66 +/- 7 years; 42% women; 11% with diabetes) who did not have aortic or mitral valve stenosis or prosthesis.RESULTS MAC was found in 458 patients (49%). Patients with MAC were older (68 +/- 7 vs. 65 +/- 7 years); were more often women (47% vs. 37%); had higher baseline systolic blood pressure (BP) (175 +/- 14 vs. 172 +/- 15 mm Hg), left atrial diameter (4.0 +/- 0.5 vs. 3.8 +/- 0.6 cm), and left ventricular mass index (58 +/- 13 vs. 55 +/- 12 g/m(2.7)) and included more patients with proteinuria (30% vs. 21%; all P < 0.01). During a mean follow-up of 4.8 years, 58 participants had an ischemic stroke. Risk of incident ischemic stroke was significantly related to presence of MAC (log rank = 9; P < 0.01). In multivariable Cox regression analysis models, MAC was associated with increased risk of ischemic stroke (hazard ratio = 1.78-2.35), independent of age, baseline or time-varying systolic BR prevalence or incidence of atrial fibrillation, history of previous cerebrovascular disease, and other well-recognized confounders, such as sex, time-varying left ventricular mass, left atrial diameter, and urinary albumin/creatinine ratio (all P < 0.05).CONCLUSIONS MAC is common in treated hypertensive patients with ECG LVH and is an independent predictor of incident ischemic stroke.

- In the Losartan Intervention for End Point Reduction in Hypertension (LIFE) study, 4.8 years' losartan- versus atenolol-based antihypertensive treatment reduced left ventricular hypertrophy and cardiovascular end points, including cardiovascular death and stroke. However, there was no difference in myocardial infarction (MI), possibly related to greater reduction in myocardial oxygen demand by atenolol-based treatment. Myocardial oxygen demand was assessed indirectly by the left ventricular massxwall stressxheart rate (triple product) in 905 LIFE participants. The triple product was included as time-varying covariate in Cox models assessing predictors of the LIFE primary composite end point (cardiovascular death, MI, or stroke), its individual components, and all-cause mortality. At baseline, the triple product in both treatment groups was, compared with normal adults, elevated in 70% of patients. During randomized treatment, the triple product was reduced more by atenolol, with prevalences of elevated triple product of 39% versus 51% on losartan (both P0.001). In Cox regression analyses adjusting for age, smoking, diabetes mellitus, and prior stroke, MI, and heart failure, 1 SD lower triple product was associated with 23% (95% confidence interval 13%-32%) fewer composite end points, 31% (18%-41%) less cardiovascular mortality, 30% (15%-41%) lower MI, and 22% (11%-33%) lower all-cause mortality (all P0.001), without association with stroke (P=0.34). Although losartan-based therapy reduced ventricular mass more, greater heart rate reduction with atenolol resulted in larger reduction of the triple product. Lower triple product during antihypertensive treatment was strongly, independently associated with lower rates of the LIFE primary composite end point, cardiovascular death, and MI, but not stroke.

- 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.

- Background: Dyspnoea is a common symptom of chronic heart failure (CHF). In the community setting, patients with CHF are most often women. Aim: To examine the impact of gender on the description of dyspnoea and to explore which clinical variables support a diagnosis of CHF. Methods: From four primary health care centres, 158 patients with CHF were included. Patients were examined with echocardiography and a cardiologist assessed the diagnosis of CHF. The patients filled in a questionnaire containing 11 descriptors of dyspnoea. Results: A diagnosis of CHF was confirmed in 87 (55%) patients (47 males and 40 females). One descriptor, I feel that I am suffocating, was significantly scored higher in CHF patients ( p=0.014) as compared to non-CHF patients. Three descriptors, My breath does not go in all the way ( p=0.006), I feel that I am suffocating ( p=0.040), and I cannot get enough air ( p=0.0327) were significantly scored higher among men with CHF, compared to no descriptor among women with CHF. Being male (OR=2.7; CI: 1.3–5.6, p=0.008), having diabetes (OR=5.6; CI: 1.7–18.2, p=0.004), IHD (OR=3.3; CI: 1.3–8.5, p=0.014), and a borderline significance for age (OR=1.04; CI: 0.99–1.08, p=0.058) predicted a confirmed diagnosis of CHF. Conclusion: Three descriptors of dyspnoea were associated with CHF among men, whereas no such association was found among women. Our results suggest that gender is an important factor and should—together with age, underlying heart disease, and diabetes—be taken into account when symptoms are evaluated in the diagnosis of CHF in primary care.

- Aim To validate a previously developed instrument for measurement of breathlessness in patients with acute heart failure (HF). METHODS AND RESULTS: We tested descriptors of breathlessness among 190 patients seeking care at the emergency department (ED) for acute shortness of breath. Out of 115 patients with confirmed HF, 107 (94%) had dyspnoea as their main symptom. There were no significant differences between those patients with HF and those who were not diagnosed as heart failure (NHF) (n = 75) in the descriptors of breathlessness, although patients with HF scored significantly (P = 0.03) higher on a visual analogue scale (VAS). In addition, they had significantly (P = 0.03) higher breathing frequency than NHF patients and they were significantly (P < 0.001) more likely to be treated with >40 mg furosemide. CONCLUSION: Assessment of acute dyspnoea using a VAS is useful in distinguishing HF from NHF, and may be a more valid approach as compared with using descriptors of intensity of breathlessness in the acute setting.
