Aims: Although balloon pulmonary angioplasty (BPA) improves haemodynamics and short-term prognosis in patients with inoperable chronic thrombo-embolic pulmonary hypertension (CTEPH), the long-term effects of BPA, and procedure-related complications remain to be fully elucidated. Methods and results: From July 2009 to October 2016, we performed a total of 424 BPA sessions in 84 consecutive patients with inoperable CTEPH. We used 3D reconstructed computed tomography to determine target lesions of pulmonary arteries and optical computed tomography to select balloon size, if needed...

Over the past two decades, the percentage of Chinese who is 60 years or older has increased from 5.2% in 1995 to 10.5% in 2015. Approximately 16% of the population in China was 60 years old and above in 2015. Since 1990, cardiovascular disease (CVD) has been the leading cause of death in China. Cardiovascular medications of older adults are usually more complicated than younger age groups due to polypharmacy, the presence of comorbidities and more susceptible to treatment-related adverse outcomes. Therefore, effective primary prevention of CVD for older adults is important in sustaining the health of older adults and reducing the burden of the healthcare system...

BACKGROUND: Functional cerebrovascular regulatory mechanisms are important for maintaining constant cerebral blood flow and oxygen supply in heathy individuals and are altered in heart failure. We aim to examine whether pulmonary arterial hypertension (PAH) is associated with abnormal cerebrovascular regulation and lower cerebral oxygenation and their physiological and clinical consequences. METHODS AND RESULTS: Resting mean flow velocity in the middle cerebral artery mean flow velocity in the middle cerebral artery (MCAvmean); transcranial Doppler), cerebral pressure-flow relationship (assessed at rest and during squat-stand maneuvers; analyzed using transfer function analysis), cerebrovascular reactivity to CO2, and central chemoreflex were assessed in 11 patients with PAH and 11 matched healthy controls...

Sarcopenia and physical deconditioning are frequent complications in patients with cirrhosis and end-stage liver disease (ESLD). They are the end result of impaired dietary intake, chronic inflammation, altered macro- and micronutrient metabolism, and low physical activity. Frailty is the end result of prolonged sarcopenia and physical deconditioning. It severely affects a patient's functional status, and presents in about 1 in 5 patients on the liver transplant (LT) waitlist. Sarcopenia, poor physical fitness/cardiopulmonary endurance, and frailty are all associated with increased mortality in ESLD...

Pulmonary hypertension (PH) is a disease characterized by progressive adverse remodeling of the distal pulmonary arteries, resulting in elevated pulmonary vascular resistance and load pressure on the right ventricle (RV), ultimately leading to RV failure. Invasive hemodynamic testing is the gold standard for diagnosing PH, and guiding patient therapy. We hypothesized that lumped-parameter and biventricular finite-element (FE) modeling may lead to noninvasive predictions of both PH-related hemodynamic and biomechanical parameters that induce PH...

Exercise training (ExT) is widely used for the prevention and treatment of several chronic cardiovascular diseases. However, only recently it started to be recognized as safe and beneficial in pulmonary arterial hypertension. Despite the consistency of its favorable effects on exercise tolerance and quality of life, the mechanisms underlying these meaningful clinical improvements remain unclear. Current studies emphasize the exercise-induced changes on skeletal muscle but the impact of ExT at the level of the pulmonary circulation and right ventricle should not be overlooked...

It is well known that chronic hypertension is accompanied by several functional deficits in the central nervous system and peripheral tissues, most of which are corrected by exercise training. However, the biological mechanisms underlying these effects are not yet well understood. In the present chapter we summarize recent experimental evidence on cellular/molecular mechanisms supporting not only the deleterious effects of hypertension on autonomic control and peripheral circulatory deficits, but also their reversion by low to moderate aerobic exercise training...

Cardiovascular dysfunction and heart failure associated with aging not only impairs the cardiac function but also the quality of life eventually decreasing the life expectancy of the elderly. Notably, cardiac tissue can prematurely age under certain conditions such as genetic mutation, persistent redox stress and overload, aberrant molecular signaling, DNA damage, telomere attrition, and other pathological insults. While cardiovascular-related morbidity and mortality is on the rise and remains a global health threat, there has been only little to moderate improvements in its medical management...

Cardiomyopathy is a serious complication of diabetes mellitus and occurs independently of coronary artery disease or hypertension. It manifests as systolic/diastolic dysfunction and hypertrophy of the left ventricle and can lead to heart failure. Hyperglycemia can trigger a series of maladaptive stimuli and result in cardiac hypertrophy, fibrosis and reduced performance and contractility. The pathogenesis of diabetic cardiomyopathy is a multifactorial process that includes metabolic derangements such as increased oxidative stress, and altered non-oxidative glucose pathways and lipid metabolism...

The non-cardiomyocyte cellular microenvironment of the heart includes diverse types of cells of mesenchymal origin. During development, the majority of these cells derive from the epicardium, while a subset derives from the endothelium/endocardium and neural crest derived mesenchyme. This subset includes cardiac fibroblasts and telocytes, the latter of which are a controversial type of "connecting cell" that support resident cardiac progenitors in the postnatal heart. Smooth muscle cells, pericytes, and endothelial cells are also present, in addition to adipocytes, which accumulate as epicardial adipose connective tissue...

Kettlebell (KB) training has become an extremely popular exercise program for improving both muscle strength and aerobic fitness. However, the cardiac autonomic modulation and blood pressure (BP) responses induced by an acute KB exercise session are currently unknown. Understanding the impact of this exercise modality on the post-exercise autonomic modulation and BP would facilitate appropriate exercise prescription in susceptible populations. The present study evaluated the effects of an acute session of KB exercise on heart rate variability (HRV) and BP responses in healthy individuals...

This prospective two-year study of patients on chronic dialysis measured changes in bone mineral density (BMD). Patients with higher baseline BMD and shorter dialysis vintage lost more bone. Treatment with anti-hypertensives acting on the central nervous system was protective against bone loss. Baseline serum levels of sclerostin and bone-specific alkaline phosphatase predicted bone loss. INTRODUCTION: This prospective 2-year study of chronic kidney disease on dialysis (CKD-5D) patients assessed trabecular and cortical bone loss at the hip and spine and examined potential demographic, clinical, and serum biochemical predictors of bone loss...

There are proven successful approaches to clinical trial design in pulmonary arterial hypertension (PAH), which in turn have led to the licensing of a number of effective therapies. SSc has been included in trials of World Health Organization Group 1 PAH but has been under-represented. Responses in outcomes as diverse as exercise capacity, quality of life, durability of drug effect and survival have been reduced in comparison with those seen in idiopathic PAH. The PAH community has achieved international and interdisciplinary consensus guidelines for future studies...

Myocardial infarction (MI) may result in pulmonary hypertension (PH). Inhibition of phosphodiesterase 5 (PDE5), the enzyme responsible for the breakdown of cGMP in vascular smooth muscle, has become part of the contemporary therapeutic armamentarium for pulmonary arterial hypertension and may also be of benefit in PH secondary to MI. Nitric oxide (NO) is an important source of cGMP and can be enhanced in early PH and decreased in severe PH. In the present study we investigated if PDE5-inhibition ameliorates pulmonary hemodynamics in swine with PH secondary to MI and whether NO is essential...

Background: Hypertension can be prevented and modified with lifestyle interventions that include regular exercise. Aquatic exercise is widely recommended for older adults for a variety of health benefits, but few studies have assessed the immediate ambulatory blood pressure (BP) response to aquatic exercise, a response termed post-exercise hypotension (PEH). Thus, we assessed PEH after a session of aquatic exercise in physically active, older women with hypertension. Methods: Twenty-four women 70...
