AI Article Synopsis

  • Exercise intolerance is a common issue in heart failure with preserved ejection fraction (HFpEF), leading to a lower quality of life and higher rates of hospitalization and mortality.
  • * The cardiopulmonary exercise test is crucial for measuring exercise tolerance and understanding the specific causes of limitations in patients with HFpEF, which can guide treatment.
  • * Exercise training programs can enhance exercise tolerance in HFpEF patients, but more research is needed to determine the most effective types and durations of these programs.*

Article Abstract

Exercise intolerance represents a typical feature of heart failure with preserved ejection fraction (HFpEF), and is associated with a poor quality of life, frequent hospitalizations, and increased all-cause mortality. The cardiopulmonary exercise test is the best method to quantify exercise intolerance, and allows detection of the main mechanism responsible for the exercise limitation, influencing treatment and prognosis. Exercise training programs improve exercise tolerance in HFpEF. However, studies are needed to identify appropriate type and duration. This article discusses the pathophysiology of exercise limitation in HFpEF, describes methods of determining exercise tolerance class, and evaluates prognostic implications and potential therapeutic strategies.

Diabetic cardiac autonomic neuropathy (CAN) is caused by damage to the autonomic nerve fibers that innervate the heart and blood vessels, leading to abnormalities in heart rate control and vascular dynamics. CAN encompasses symptoms such as exercise intolerance, orthostatic hypotension, cardiac denervation syndrome, and nocturnal hypertension. Neurogenic orthostatic hypotension (nOH), resulting from severe diabetic CAN, can cause symptomatic orthostatic hypotension.

Background: Left bundle branch block (LBBB) is a rare conduction disorder in athletes associated with ventricular dyssynchrony, which can lead to left ventricular systolic dysfunction and exercise intolerance. Inappropriate sinus tachycardia (IST) is characterized by an excessive heart rate (HR) that is not related to physiological needs, often resulting in reduced exercise capacity. Managing these conditions in athletes can be challenging, as standard treatments like beta-blockers and ivabradine, while effective in controlling HR, are described to be associated with a reduction in maximal exercise performance.

Heart failure with preserved ejection fraction (HFpEF) is increasingly common but its pathogenesis is poorly understood. The ability to assess genetic and pharmacologic interventions is hampered by the lack of robust preclinical mouse models of HFpEF. We developed a novel "two-hit" model, which combines obesity and insulin resistance with chronic pressure overload to recapitulate clinical features of HFpEF.

Pantothenate kinase 4 controls skeletal muscle substrate metabolism.

Article Synopsis
  • Metabolic flexibility in skeletal muscle is crucial for healthy glucose and lipid metabolism, and its dysfunction can lead to metabolic diseases.
  • Exercise improves metabolic flexibility and helps identify mechanisms that support metabolic health.
  • The study reveals that pantothenate kinase 4 (PanK4) is vital for muscle metabolism, as its deletion disrupts fatty acid oxidation and elevates harmful acetyl-CoA levels, which lead to glucose intolerance, while increasing PanK4 enhances glucose uptake and lowers acetyl-CoA.

Chronotropic incompetence (CTI), the inability of the heart to increase its rate with increased activity, leads to exercise intolerance and predicts overall mortality. We previously reported that cardiac β-adrenergic receptor downregulation occurs in patients with CTI without heart failure (HF), indicating postsynaptic sympathetic nervous dysfunction. However, cardiac presynaptic sympathetic nervous system function in CTI is not fully understood.
