Physical exercise is commonly regarded as protective against cardiovascular disease (CVD). Recent studies have reported that exercise alters the gut microbiota and that modification of the gut microbiota can influence cardiac function. Here, we focused on the relationships among exercise, the gut microbiota and cardiac function after myocardial infarction (MI). Four-week-old C57BL/6J mice were exercised on a treadmill for 4 weeks before undergoing left coronary artery ligation. Cardiac function was assessed using echocardiography...

BACKGROUND: Hospital length of stay after acute myocardial infarction (AMI) treated with primary percutaneous coronary intervention (pPCI) has reduced, resulting in more limited patient education during admission. Therefore, systematic participation in cardiac rehabilitation (CR) has become more essential. We aimed to identify patient-related factors that are associated with participation in and completion of a CR programme. METHODS: We identified 3,871 consecutive AMI patients who underwent pPCI between 2003 and 2011...

Here we aimed to compare the beneficial effects of T3 and T4 hormone treatment to those provided by aerobic exercise training in Wistar rats post-myocardial infarction (MI). Rats in one group were SHAM-operated and in the other group were subjected to MI surgery. One week after surgery, the MI group animals either received T3 and T4 hormones by gavage or underwent a low intensity aerobic exercise training protocol on a treadmill, and both treatments lasted until 10 weeks after MI. Untreated SHAM-operated and MI groups were also followed for the same duration...

OBJECTIVE: This study aimed to investigate the effect of specialized prevention clinics and standard clinics follow-ups on secondary protection after acute coronary syndrome (ACS) on cardiovascular risk factors. METHODS: A total of 118 patients who received thrombolytic therapy after being diagnosed with ST-segment elevation myocardial infarction were followed up for 6 months. After ACS, patients in a specialized prevention clinic (Group 1) (n=67) and those in a standard clinic (Group 2) (n=51) were compared in terms of the change in their lifestyle, management of risk factors, and drug compliance...

Exercise training has been demonstrated to have beneficial effects in patients with heart failure (HF) or diabetes. However, it is unknown whether diabetic patients with HF will benefit from exercise training. Male Wistar rats were fed either a standard (Sham, n= 53) or high-fat, high-sucrose (HFHS) diet (D, n=66) for 6 months. After 2 months of diet, the rats were already diabetic. Rats were then randomly subjected to either myocardial infarction by coronary artery ligation (MI) or sham operation (Sham). Two months later, heart failure was documented by echocardiography and animals were randomly subjected to exercise training with treadmill for eight additional weeks or remained sedentary...

Background Endurance exercise training induces cardio-protective effects, but athletes are not exempted from a myocardial infarction. Evidence from animal studies suggests that exercise training attenuates pathological left ventricular remodelling following myocardial infarction. We tested the hypothesis that lifelong exercise training is related to attenuated pathological left ventricular remodelling after myocardial infarction as evidenced by better left ventricular systolic function in veteran athletes compared to sedentary peers...

Studies of adverse events (AEs) after orthopedic surgery commonly use composite AE outcomes. An example of such an outcome is any AE. These types of outcomes treat AEs with different clinical significance (eg, death, urinary tract infection) similarly. We conducted a study to address this shortcoming in research methodology by creating a single severity-weighted outcome that can be used to characterize the overall severity of a given patient's postoperative course. All orthopedic faculty members at 2 academic institutions were invited to complete a severity-weighting exercise in which AEs were assigned a percentage severity of death...

Oxygen uptake (VO2 ) and exercise tolerance in rats classified by myocardial infarction (MI) size are underexplored. The aim of this study was to evaluate VO2 /carbon dioxide production (VCO2 ) and exercise tolerance in rats that have undergone MI. Fourteen weeks after MI or sham surgery, rats underwent an integrated approach to left ventricular function and VO2 /VCO2 , exercise tolerance and skeletal muscle weight evaluation. Based on MI size determination, rats were assigned to sham operated controls (Sham, n = 12), small myocardial infarction (SMI, n = 8), and large myocardial infarction (LMI, n = 5) groups...

Heart disease is the leading cause of death in the United States (1). Each year, approximately 790,000 adults have a myocardial infarction (heart attack), including 210,000 that are recurrent heart attacks (2). Cardiac rehabilitation (rehab) includes exercise counseling and training, education for heart-healthy living, and counseling to reduce stress. Cardiac rehab provides patients with education regarding the causes of heart attacks and tools to initiate positive behavior change, and extends patients' medical management after a heart attack to prevent future negative sequelae (3)...

Exercise training is a potent, therapeutic approach in obesity and diabetes that exerts protective effects against development of diabetic cardiomyopathy and ischemic-injury. Acute increases in circulating fatty acids (FAs) during an ischemic insult can challenge the heart, as high FA-load is considered to have adverse cardiac effects. In the present study, we tested the hypothesis that exercise-induced cardiac effects in diet-induced obese mice are abrogated by an acute high FA-load. Diet-induced obese mice were fed a high-fat diet (HFD) for 20 weeks...

BACKGROUND: Cardiovascular disease remains the leading cause of morbidity and mortality worldwide, and there is a rising global burden. The effects of diet on cardiometabolic risk factors have been studied extensively. Healthy eating as a cost-effective approach to risk reduction in post-myocardial infarction patients is proven to be beneficial, and the "plate model" is one of the practical methods to achieve this objective. METHODS/DESIGN: The study will be conducted as a randomized, single-blind, controlled clinical trial for a period of 3 months...

BACKGROUND: Cardiovascular disease is the most common cause of death globally. Traditionally, centre-based cardiac rehabilitation programmes are offered to individuals after cardiac events to aid recovery and prevent further cardiac illness. Home-based cardiac rehabilitation programmes have been introduced in an attempt to widen access and participation. This is an update of a review previously published in 2009 and 2015. OBJECTIVES: To compare the effect of home-based and supervised centre-based cardiac rehabilitation on mortality and morbidity, exercise-capacity, health-related quality of life, and modifiable cardiac risk factors in patients with heart disease...

Background Coronary risk factor control in Europe is suboptimal and there are large variations in the nature of cardiac rehabilitation (CR) programmes offered to coronary heart disease patients. We aim to explore characteristics and risk factor control in patients recruited from two neighbouring hospitals offering CR with different content. Methods In a cross-sectional study, 1127 Norwegian patients hospitalized with acute myocardial infarction and/or a revascularization procedure attended a clinical visit and completed a questionnaire at 2-36 months' follow-up...

Cardiac rehabilitation is a well-defined multidisciplinary program with the objective to reduce mortality and morbidity, while also improving the exercise capacity and quality of life of the patient following a myocardial infarction. Despite the fact that a cardiovascular rehabilitation program is now recommended by international guidelines for all patients who have suffered from an acute coronary syndrome, only half of all patients actually participate to such a program in Switzerland. Even worse, especially when taking into consideration the population in Geneva, less than 5 % of patients follow a long-term cardiac maintenance program (phase III)...

Patients with myocardial infarction with nonobstructive coronary arteries (MINOCA), including Takotsubo syndrome (TS), are considered to have a better survival compared with those with coronary heart disease (CHD). Studies of patients with MINOCA measuring physical and mental function including matched control groups are lacking. The aim of this study was to determine the physical capacity and quality of life in patients with MINOCA. One-hundred patients with MINOCA along with TS (25%) were investigated from 2007 to 2011...

We previously reported that facilitating the clearance of damaged mitochondria through macroautophagy/autophagy protects against acute myocardial infarction. Here we characterize the impact of exercise, a safe strategy against cardiovascular disease, on cardiac autophagy and its contribution to mitochondrial quality control, bioenergetics and oxidative damage in a post-myocardial infarction-induced heart failure animal model. We found that failing hearts displayed reduced autophagic flux depicted by accumulation of autophagy-related markers and loss of responsiveness to chloroquine treatment at 4 and 12 wk after myocardial infarction...

BACKGROUND: Lipolysis is stimulated by activation of adrenergic inputs to adipose tissues. Our recent study showed that serum concentrations of fatty acid binding protein 4 (FABP4) are robustly elevated in patients with acute myocardial infarction and ventricular tachyarrhythmia, that display a marked activation of the sympathetic nervous system (SNS). However, it remains unknown whether circulating FABP4 concentrations are associated with exercise-induced SNS activation. METHODS: Thirty one healthy volunteers underwent cardiopulmonary exercise testing on a cycle ergometer up to the workload levels below and above anaerobic threshold, low- and high-intensity exercise, respectively...
