Background Chronic heart failure (CHF) is an established risk factor of atrial fibrillation (AF), but the prognostic value of cardiac and hemodynamic parameters in assessing the risk of developing AF among patients with CHF is less defined. Methods and results We followed an outpatients cohort of CHF patients secondary to left ventricular (LV) systolic dysfunction, who were free of AF at baseline. All patients underwent clinical evaluation, comprehensive echocardiography, and blood drawing in the same morning. Aortic pulse wave velocity (aPWV), a measure of aortic stiffness, was determined by Doppler echocardiography. A total of 77 patients (age 63 ± 9 years; 79% male) with mean LVEF (34 ± 8%) formed the study population. Fifteen patients developed incidental AF. At baseline, CHF patients who developed AF during follow‐up had higher E‐wave velocity (75 ± 2 cm/sec vs. 60 ± 2 cm/sec; P = 0.02), higher difference duration between mitral and pulmonary vein A velocity (A′–A), (10 ± 35 msec vs. 43 ± 44 msec P = 0.02), aPWV (7.1 ± 2.6 vs. 5.3 ± 1.9 m/sec P = 0.004), and furosemide dosage (110 ± 145 mg vs. 49 ± 48 mg P = 0.01) than those remaining free from AF. The two groups of patients did not significantly differ in terms of NYHA, LV volumes, ejection fraction, left atrial volume, creatinine, hemoglobin, renin, epinephrine, amino‐terminal propeptide of type III and I procollagens, ACE inhibitor, and β‐blocker dose (P > 0.1 for all). Notably, higher aPWV (P = 0.01) and longer A–A′ duration (P = 0.04) were associated with an increased incidence of AF, independently of potential confounders. Conclusions Increased aortic stiffness and LV diastolic dysfunction are strong predictors of new onset of AF among patients with systolic CHF.

A 67-year-old woman was admitted to our hospital because of the recent onset of dyspnoea.

We read with interest the recent article by Juutilainen et al. (1) showing that proliferative retinopathy in both sexes and nonproliferative retinopathy in women independently predict all-cause and cardiovascular disease (CVD)-associated death. The authors have cautiously concluded that the sex difference observed in the association between nonproliferative retinopathy and cardiovascular death needs to be confirmed in larger studies. Indeed, I think the relatively low frequency of retinopathy (23%) and the relatively high cut-off chosen for diagnosing hypertension (blood pressure ≥160/95 mmHg or treatment) could be …

OBJECTIVE—To determine the prevalence of nonalcoholic fatty liver disease (NAFLD) in type 2 diabetic population and to compare the prevalence of cardiovascular disease (CVD) and its risk factors between people with and without NAFLD. RESEARCH DESIGN AND METHODS—The entire sample of type 2 diabetic outpatients (n = 2,839) who regularly attended our clinic was screened. Main outcome measures were NAFLD (by patient history and liver ultrasound) and manifest CVD (by patient history, review of patient records, electrocardiogram, and echo-Doppler scanning of carotid and lower limb arteries). RESULTS—The unadjusted prevalence of NAFLD was 69.5% among participants, and NAFLD was the most common cause (81.5%) of hepatic steatosis on ultrasound examination. The prevalence of NAFLD increased with age (65.4% among participants aged 40–59 years and 74.6% among those aged ≥60 years; P < 0.001) and the age-adjusted prevalence of NAFLD was 71.1% in men and 68% in women. NAFLD patients had remarkably (P < 0.001) higher age and sex-adjusted prevalences of coronary (26.6 vs. 18.3%), cerebrovascular (20.0 vs. 13.3%), and peripheral (15.4 vs. 10.0%) vascular disease than their counterparts without NAFLD. In logistic regression analysis, NAFLD was associated with prevalent CVD independent of classical risk factors, glycemic control, medications, and metabolic syndrome features. CONCLUSIONS—NAFLD is extremely common in people with type 2 diabetes and is associated with a higher prevalence of CVD. Follow-up studies are needed to determine whether NAFLD predicts the development and progression of CVD.

Non‐alcoholic fatty liver disease (NAFLD) affects a substantial proportion of the general population and is frequently associated with many features of the metabolic syndrome (MetS). Currently, the importance of NAFLD and its relationship with the MetS is being increasingly recognized, and this has stimulated an interest in the possible role of NAFLD in the development of atherosclerosis. Recent studies have reported the association of NAFLD with multiple classical and non‐classical risk factors for cardiovascular disease (CVD). Moreover, there is a strong association between the severity of liver histopathology in NAFLD patients and greater carotid artery intima‐media thickness and plaque, and lower endothelial flow‐mediated vasodilation (as markers of subclinical atherosclerosis) independent of obesity and other MetS components. Finally, it has recently been demonstrated that NAFLD is associated with an increased risk of all‐cause death and predicts future CVD events independently of other prognostic factors, including MetS components. Overall, therefore, the evidence from these recent studies strongly emphasizes the importance of assessing the global CVD risk in patients with NAFLD. Moreover, these novel findings suggest a more complex picture and raise the possibility that NAFLD, as a component of the MetS, might not only be a marker but also an early mediator of CVD.
