The difference between men and women is clear even just by looking at an electrocardiogram: females present higher resting heart rate, a shorter QRS complex length and greater corrected QT interval. The development of these differences from pubertal age onward suggests that sexual hormones play a key role, although their effect is far from being completely understood. Different incidences between sexes have been reported for many arrhythmias, both ventricular and supraventricular, and also for sudden cardiac death...

Cardiac function, skeletal (soleus) muscle oxidative metabolism and the effects of exercise training were evaluated in a transgenic murine model (Tgαq*44) of chronic heart failure (CHF) during the critical period between the occurrence of an impairment of cardiac function and the stage at which overt cardiac failure ensues (i.e. from 10 to 12 months of age). Forty-eight Tgαq*44 mice and 43 wild-type (WT) FVB controls were randomly assigned to control groups and to groups undergoing 2 months of intense exercise training (spontaneous running on a instrumented wheel)...

Heart failure (HF) is a common end point for numerous cardiovascular conditions, including coronary artery disease, valvular disease, and hypertension. HF predominantly affects older individuals (aged ≥70 years), particularly those living in developed countries. The pathophysiological sequelae of HF progression have a substantial negative effect on physical function. Diminished physical function in older patients with HF, which is the result of combined disease-related and age-related effects, has important implications on health...

Heart failure with preserved ejection fraction (HFpEF) is a common disease with high incidence and increasing prevalence. Patients suffer from functional limitation, poor health-related quality of life, and reduced prognosis. A pilot study in a smaller group of HFpEF patients showed that structured, supervised exercise training (ET) improves maximal exercise capacity, diastolic function, and physical quality of life. However, the long-term effects of ET on patient-related outcomes remain unclear in HFpEF. The primary objective of the Exercise training in Diastolic Heart Failure (Ex-DHF) trial is to investigate whether a 12 month supervised ET can improve a clinically meaningful composite outcome score in HFpEF patients...

Overweight and obesity are well-established risk factors for most cardiovascular diseases (CVD), including coronary heart disease (CHD), heart failure (HF), and atrial fibrillation. Despite the strong link between excess adiposity and risk of CVD, growing evidence has demonstrated an obesity paradox in patients with CVD. This phenomenon is characterized by a better prognosis in overweight and mildly obese CVD patients than their leaner counterparts. Moreover, the worst outcomes are often incurred by underweight CVD patients, followed by those of normal weight or severely obese...

There is substantial causal and consequential interaction between the ever-growing heart failure and renal failure patients. Half of the patients with heart failure (HF) have preserved left ventricular ejection fraction (HFpEF), which is difficult to diagnose and rising in prevalence relative to HF with reduced EF (HFpEF). To date, only weight reduction, exercise training, and diuretics have been shown to improve exercise tolerance and morbidity in HFpEF. This review aims to establish the baseline kidney-related concepts specific to the diagnosis and treatment of HFpEF patients and the different aspects of HFpEF and HFpEF in the clinical setting...

Exercise elicits coordinated multi-organ responses including skeletal muscle, vasculature, heart, and lung. In the short term, the output of the heart increases to meet the demand of strenuous exercise. Long-term exercise instigates remodeling of the heart including growth and adaptive molecular and cellular re-programming. Signaling pathways such as the insulin-like growth factor 1/PI3K/Akt pathway mediate many of these responses. Exercise-induced, or physiologic, cardiac growth contrasts with growth elicited by pathological stimuli such as hypertension...

BACKGROUND: Although aerobic exercise improves quality of life as assessed by a disease-specific instrument in ambulatory HF patients with a reduced ejection fraction (EF), the impact of an exercise intervention on general health status has not been previously reported. METHODS: A secondary analysis was performed of the HF-ACTION trial (ClinicalTrials.gov Number: NCT00047437), which enrolled 2331 medically stable outpatients with HF and an EF ≤35% and randomized them to aerobic exercise training, consisting of 36 supervised sessions followed by home-based training versus usual care for a median follow-up of 30 months...

Background Exercise oscillatory ventilation in chronic heart failure has been suggested as a factor related to adverse cardiac events, aggravated prognosis and higher mortality. Exercise training is well known to affect exercise capacity and mechanisms of pathophysiology beneficially in chronic heart failure. Little is known, however, about the exercise training effects on characteristics of exercise oscillatory ventilation in chronic heart failure patients. Design and methods Twenty (out of 38) stable chronic heart failure patients exhibited exercise oscillatory ventilation (age 54 ± 11 years, peak oxygen uptake 15...

Body wasting is a serious complication that affects a large proportion of patients with heart failure. Muscle wasting, also known as sarcopenia, is the loss of muscle mass and strength, whereas cachexia describes loss of weight. After reaching guideline-recommended doses of heart failure therapies, the most promising approach to treating body wasting seems to be combined therapy that includes exercise, nutritional counselling, and drug treatment. Nutritional considerations include avoiding excessive salt and fluid intake, and replenishment of deficiencies in trace elements...

Cachexia in the context of heart failure (HF) has been termed cardiac cachexia, and represents a progressive involuntary weight loss. Cachexia is mainly the result of an imbalance in the homeostasis of muscle protein synthesis and degradation due to a lower activity of protein synthesis pathways and an over-activation of protein degradation. In addition, muscle wasting leads to of impaired functional capacity, even after adjusting for clinical relevant variables in patients with HF. However, there is no sufficient therapeutic strategy in muscle wasting in HF patients and very few studies in animal models...

Cachexia is a wasting syndrome observed in many patients suffering from several chronic diseases including cancer. In addition to the progressive loss of skeletal muscle mass, cancer cachexia results in cardiac function impairment. During the severe stage of the disease, patients as well as animals bearing cancer cells display cardiac atrophy. Cardiac energy metabolism is also impeded with disruption of mitochondrial homeostasis and reduced oxidative capacity, although the available data remain equivocal. The release of inflammatory cytokines by tumor is a key mechanism in the initiation of heart failure...

Implantation of left ventricular assist devices (LVAD) has increased because of improved safety profile and limited availability of heart transplantation. Although supervised exercise training (ET) programs are known to improve exercise capacity and quality of life (QoL) in heart failure (HF) patients, similar data is inconclusive in LVAD patients. Thus, we performed a systematic review on studies that incorporated supervised ET and measured peak oxygen uptake in LVAD patients. A total of 150 patients in exercise and 55 patients in control groups were included from 8 studies selected from our predefined criteria...
