How does exercise affect cardiovascular disease?
Regular physical activity reduces the risk of dying prematurely from CVD. It also helps prevent the development of diabetes, helps maintain weight loss, and reduces hypertension, which are all independent risk factors for CVD.
Why diet reduces the risk of cardiovascular disease?
Sodium and potassium are two interrelated minerals that play major roles in regulating blood pressure and a healthy heart. Eating less salty foods and more potassium-rich foods may significantly lower the risk of cardiovascular disease.
How does exercise reduce risk of cardiovascular disease?
Improves the muscles' ability to pull oxygen out of the blood, reducing the need for the heart to pump more blood to the muscles. Reduces stress hormones that can put an extra burden on the heart. Works like a beta blocker to slow the heart rate and lower blood pressure.
Why is diet and exercise important to the functioning of the heart?
Diet and exercise are an important part of your heart health. If you don't eat a good diet and you don't exercise, you are at increased risk of developing health problems. These include high blood pressure, high cholesterol, obesity, type 2 diabetes, and heart disease.
Is exercise good for cardiovascular disease?
Being physically active is a major step toward good heart health. It's one of your most effective tools for strengthening the heart muscle, keeping your weight under control and warding off the artery damage from high cholesterol, high blood sugar and high blood pressure that can lead to heart attack or stroke.
What dietary change could help prevent cardiovascular disease?
Vegetables and fruits are also low in calories and rich in dietary fiber. Vegetables and fruits, like other plants or plant-based foods, contain substances that may help prevent cardiovascular disease. Eating more fruits and vegetables may help you cut back on higher calorie foods, such as meat, cheese and snack foods.
What are the causes of cardiovascular diseases?

How does cardiovascular disease affect the world?
Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide. In the United States, CVD accounts for ~600,000 deaths (25%) each year (1, 2), and after a continuous decline over the last 5 decades, its incidence is increasing again (3). Among the many risk factors that predispose to CVD development and progression, a sedentary lifestyle, characterized by consistently low levels of physical activity, is now recognized as a leading contributor to poor cardiovascular health. Conversely, regular exercise and physical activity are associated with remarkable widespread health benefits and a significantly lower CVD risk. Several long-term studies have shown that increased physical activity is associated with a reduction in all-cause mortality and may modestly increase life expectancy, an effect which is strongly linked to a decline in the risk of developing cardiovascular and respiratory diseases (4). Consistent with this notion, death rates among men and women have been found to be inversely related to cardiorespiratory fitness levels, even in the presence of other predictors of cardiovascular mortality such as smoking, hypertension, and hyperlipidemia (5). Moreover, better fitness levels in both men and women can partially reverse the elevated rates of all-cause mortality as well as CVD mortality associated with high body mass index (6, 7). Recent work from cardiovascular cohorts shows that sustained physical activity is associated with a more favorable inflammatory marker profile, decreases heart failure risk, and improves survival at 30 years follow-up in individuals with coronary artery disease (8–10).
How does the heart respond to exercise?
During exercise, the heart is subjected to intermittent hemodynamic stresses of pressure overload, volume overload, or both. To normalize such stress and to meet the systemic demand for an increased blood supply, the heart undergoes morphological adaptation to recurrent exercise by increasing its mass, primarily through an increase in ventricular chamber wall thickness. This augmentation of heart size is primarily the result of an increase in the size of individual terminally differentiated cardiac myocytes (75). Adaptive remodeling of the heart in response to exercise typically occurs with preservation or enhancement of contractile function. This contrasts with pathologic remodeling due to chronic sustained pressure overload (e.g., during hypertension or aortic stenosis), which can proceed to a loss of contractile function and heart failure (76).
How does the resistance arterial network adapt to exercise?
The resistance arterial vascular network also undergoes functional and structural adaptation to exercise (109). During acute exercise, small arteries and pre-capillary arterioles that supply blood to the skeletal muscles must dilate to increase blood flow through the release of vasodilatory signals (e.g., adenosine, lactate, K+, H+, CO2) from active surrounding muscle (110–112). Repeated exercise leads to an adaptive response in skeletal muscle arterioles that includes increased vascular density coupled with greater vasodilatory capacity, such that enhanced perfusion can occur after conditioning (113–116). This may be partly due to adaptation of the endothelium to the complex interplay of recurrent variations in hemodynamic stresses and vasodilatory stimuli of exercise. Endothelial synthesis of NO is greatly increased at rest and during exercise in conditioned individuals/animals (117). A similar adaptive response to exercise has also been noted in the coronary vasculature, which must dilate to meet the increased metabolic demands of the myocardium (118). Exercise-trained humans and animals demonstrate reduced myocardial blood flow at rest, which may reflect a reduction in cardiac oxygen consumption primarily as a result of lower resting heart rate (119, 120). However, a large body of evidence suggests that multiple mechanisms converge to enhance the ability of the coronary circulation to deliver a greater supply of oxygen to the conditioned myocardium during exercise. This includes structural adaptations consisting of an expansion in the density of intramyocardial arterioles and capillaries as well as enhanced microvascular collateral formation (121–124). Additionally, like skeletal muscle arterioles, coronary arterial network enhances its responsiveness to vasoactive stimuli via a number of distinct mechanisms including, but not limited to, augmentation of endothelial NO production, altered responsiveness to adrenergic stimuli, or changes in the metabolic regulation of vascular tone (125–127). In addition, some studies implicate hydrogen peroxide (H2O2)-mediated vasodilation in opposing exertion-induced arterial dysfunction in overweight obese adults after a period of exercise training (128, 129), suggesting enhanced contribution of NO-independent mechanisms to improved microvascular endothelial function with exercise. Collectively, these adaptations may act to support enhanced myocardial function and increased cardiac output during repeated exercise, and increased total body oxygen demand following exercise conditioning. Further advancement of our understanding of how blood flow is improved in response to exercise could lead to novel therapeutic strategies to prevent or reverse organ failure in patients resulting from inadequate blood flow.
What causes electrical instability in the heart?
During pathologic remodeling of the heart, electrical instability can result from a lack of upregulation of key cardiac ion channel subunits associated with action potential repolarization relative to an increase in myocyte size (94). In contrast, increased myocyte size in physiological hypertrophy is associated with the upregulation of depolarizing and repolarizing currents, which may be protective against abnormal electrical signaling in the adapted heart (95, 96). For example, cardiac myocytes isolated from mice after 4 weeks of swim training were found to have elevated outward K+current densities (i.e., Ito,f, IK,slow, Iss, and IK1) and increased expression of underlying molecular component Kv and Kir subunits in parallel with increases in total protein levels (96). Interestingly, a follow up study found that while increases in K+channel subunit expression following exercise training requires PI3K, these changes occur independently of Akt1 and hypertrophy (97).
What is the effect of shear forces on skeletal muscle?
Contributing to this effect, shear forces, as well as released metabolites from active skeletal muscle during exercise, signal the production and release of nitric oxide (NO) and prostacyclin from the vascular endothelium, which promotes enhanced vasodilation via relaxation of vascular smooth muscle cells (66).
Does plaque quality affect cardiovascular risk?
In contrast, other studies report greater plaque stability due to calcification in exercisers, thus indicating that with higher levels of physical activity, plaque quality may be favorably impacted to lower the risk of cardiovascular events, despite a higher incidence of plaques and normal CAC scores (135, 136).
Does exercise increase cardiac output?
In addition to metabolic and molecular remodeling, exercise can also promote functional adaptation of the heart, which may ultimately increase cardiac output and reduce the risk of arrhythmia. Clinical studies have shown that exercise-trained individuals have improved systolic and diastolic function (85, 86), while results of studies using animal models of exercise show that endurance exercise promotes enhanced cardiomyocyte contraction-relaxation velocities and force generation (87–90). This effect of exercise on cardiomyocyte contractile function may be related to alterations in the rise and decay rates of intracellular Ca2+transients, possibly due to enhanced coupling efficiency between L-type Ca2+channel-mediated Ca2+entry and activation of subsarcolemmal ryanodine receptors (RyR; i.e., calcium-induced calcium release), and increased expression and activity of the sarcoendoplasmic reticulum Ca2+ATPase (SERCA2a) and sodium-calcium exchanger (NCX) (88, 91, 92). In addition, the sensitivity of the cardiomyocyte contractile apparatus may also become more sensitive to Ca2+, thus producing a greater force of contraction at a given [Ca2+]i, following exercise, (93). These changes may at least partially depend on upregulation of the Na+/H+antiporter and altered regulation of intracellular pH.
What are cardiovascular diseases?

How does exercise help with cardiovascular disease?
Exercise prevents both the onset and development of cardiovascular disease and is an important therapeutic tool to improve outcomes for patients with cardiovascular disease. Some benefits of exercise include enhanced mitochondrial function, restoration and improvement of vasculature, and the release of myokines from skeletal muscle that preserve or augment cardiovascular function. In this review we will discuss the mechanisms through which exercise promotes cardiovascular health.
How does exercise affect health?
Several recent studies have shown that sustained physical activity is associated with decreased markers of inflammation, improved metabolic health, decreased risk of heart failure, and improved overall survival (15–17). Exercise improves overall metabolic health and reduces the development of T2D (18) by improving glucose tolerance (19), insulin sensitivity (20), and decreasing circulating lipid concentrations (21). This occurs primarily through adaptations to the skeletal muscle, liver, and adipose tissue (16, 22, 23). Physical exercise can also improve cardiovascular function through adaptations to the heart and vascular system (17, 24–27). Regular physical exercise decreases resting heart rate, blood pressure, and atherogenic markers, and increases physiological cardiac hypertrophy (13–15, 28). Exercise improves myocardial perfusion and increases high-density lipoprotein (HDL) cholesterol levels, all of which reduce stress on the heart and improve cardiovascular function in healthy and diseased individuals (11, 15, 29, 30). Given the increasing interest in exercise-based therapies, we will discuss the benefits of exercise on cardiovascular health and the potential mechanisms through which they occur.
How does IL-6 affect the body?
IL-6 was introduced as the first myokine over a decade ago (197). Circulating levels of IL-6 are increased in response an acute bout of aerobic exercise (198, 199) and can act in an endocrine fashion to improve metabolic and cardiovascular health. Exercise-induced elevated concentrations of IL-6 can stimulate glucagon-like peptide-1 (GLP-1) secretion from intestinal L cells and pancreatic α cells, leading to improvements in insulin secretion and glycemia (188). IL-6 also increases lipolysis and fatty acid oxidation in adipose tissue (189) and can increase glucose uptake through stimulation of the AMP-activated protein kinase (AMPK) signaling pathway (190, 191). With regard to cardiovascular function, IL-6 can reduce inflammation by inhibiting tumor necrosis factor-α (TNF- α) (186). This results in a protective effect on cardiovascular health because TNF- α is involved in the formation of atherosclerosis, development of heart failure, and subsequent complications, including myocardial infarction (MI) (187). More investigation is required to determine the direct effects of IL-6 action on cardiovascular health.
How does high intensity exercise affect heart failure?
More recent studies have examined the effects of high-intensity exercise on patients with heart failure. A recent study found that 12 weeks of high intensity interval training (HIIT) in heart failure patients (with reduced ejection fraction) was well-tolerated and had similar benefits compared to patients who underwent moderate continuous exercise (MCE) training, including improved left ventricular remodeling and aerobic capacity (105). A separate study found that 4 weeks of HIIT in heart failure patients with preserved ejection fraction improved VO2peakand reduced diastolic dysfunction compared to both pre-training values and compared to the MCE group (78). These studies indicate that both moderate and high intensity exercise training improve cardiovascular function in heart failure patients, likely related to increased endothelium-dependent vasodilation (106) and improved aerobic capacity (78, 101, 105).
How does exercise help with metabolic syndrome?
Individuals with metabolic syndrome who participated in a 4 month program of either a diet (caloric restriction) or exercise intervention had reduced adiposity, decreased systolic, diastolic and mean arterial blood pressure, and lower total and low-density lipoprotein (LDL) cholesterol lipid profiles compared to the control group (12). Both the diet and exercise intervention improve these cardiovascular outcomes to a similar extent (74).
What happens to the left ventricle afterload?
Sustained hypertension increases left ventricular afterload, forcing the left ventricle to work harder (45). This leads to pathologic hypertrophy of the ventricular walls and ventricular chamber dilation, eventually culminating in decreased myocardial function and the onset of heart failure (46, 47). As myocardial function declines, the cardiovascular system becomes impaired, resulting in insufficient blood flow. Oxygen and nutrients are then unable to meet the physiological demands of the body, resulting in tachycardia and extreme fatigue, as well as compounding health issues such as pulmonary congestion, fluid retention, and arrhythmias (48, 49).
What is the leading cause of death worldwide?
Cardiovascular disease ( CVD) is the leading cause of morbidity and mortality worldwide (31, 32). Almost half of all adults in the United States have at least one key risk factor for development of CVD (i.e., high blood pressure, high cholesterol, or smoking) (33). CVD encompasses a wide range of conditions that affect the heart and vasculature including arrhythmias, dilated, hypertrophic, or idiopathic cardiomyopathies, heart failure and atherosclerosis (34, 35). These conditions can lead to potentially fatal cardiac events such as stroke, myocardial infarction (heart attack), or cardiac arrest (31, 36). Thus, determining various therapeutic tools to prevent or reduce the incidence of CVD is vital.

How to burn more calories in a day?
Your exercise can be done all at one time, or intermittently over the day. Initial activities may be walking or swimming at a slow pace. You can start out by walking 30 minutes for three days a week and can build to 45 minutes of more intense walking, at least five days a week. With this regimen, you can burn 100 to 200 calories more per day. All adults should set a long-term goal to accumulate at least 30 minutes or more of moderate-intensity physical activity on most, and preferably all, days of the week. This regimen can be adapted to other forms of physical activity, but walking is particularly attractive because of its safety and accessibility. Also, try to increase “every day” activity such as taking the stairs instead of the elevator. Reducing sedentary time is a good strategy to increase activity by undertaking frequent, less strenuous activities. With time, you may be able to engage in more strenuous activities. Competitive sports, such as tennis and volleyball, can provide an enjoyable form of exercise for many, but care must be taken to avoid injury.
