What Is Cardiovascular Disorder

To understand Cardiovascular disorder we have to study the function of cardiovascular system. Functions of the cardiovascular system include (1) transporting nutrients to cells, (2) removing waste products through the intestines and other excretory organs, and (3) pumping oxygenated blood from the heart via the arteries and returning deoxygenated blood via the veins. The cardiovascular system works in tandem with the respiratory and nervous systems. It works with the respiratory system by taking the oxygen inhaled into the lungs to the rest of the body, and delivering carbon dioxide from the body to the lungs for expulsion. Impulses from the the sympathetic and parasympathetic nervous systems help regulate the heartbeat.

The heart is a cone-shaped organ, about the size of a clenched fist. Contrary to popular belief, the heart is not on the left side of the chest; it is almost central, but its most prominent pulsation is felt beneath the left nipple. It pumps blood throughout the body and averages 70 beats per minute in an average adult. This is accomplished via nerve impulses and contractions of muscles. The heart is loosely enclosed in a fibrous, protective, bag-like enclosure called the pericardium. The heart is comprised of 4 chambers. The top portion houses the atrium, of which there are right and left valves. The bottom portion of the heart contains the chamber known as the ventricle, of which there are also right and left valves.

Cardiovascular disease comprises of several symptoms and disorders; coronary artery disease (including arteriosclerosis, atherosclerosis, angina and myocardial infarction), hypertension, rheumatic heart disease and congenital heart disease. Coronary artery disease is the most frequent cause of death from cardiovascular disease.

In modern system of medicine, the drugs often used in the treatment are antiarrhythmics, antihypertensives, antiadrenergics, diuretics, antianginals and anticoagulants. These drugs are effective but have a number of side effects like severe headaches, mild constipation, shortness of breath, dizziness, loss of appetite, heartburn etc. In chronic cases, the treatment is obviously prolonged. 

The herbal system has a number of medicines that not only provide symptomatic relief but attacks the root cause without any known side effects. so we should try some herbal and alternate medicines also by consulting the experts.

7 Ways to prevent cardiovascular disease

7 Ways to prevent cardiovascular disease - Heart disease and stroke are some examples of cardiovascular disease. Stress, lifestyle, and diet are often the cause of this disease. So how do I prevent it? Listen more, as reported by the following Idiva.

Routine inspection

Most cardiovascular diseases strike suddenly without any symptoms. Before its too late, it would be better if your routine check-ups or medical examination to know the hidden risk of cardiovascular disease.

Yoga

Through yoga breathing exercises is one way to prevent cardiovascular disease. Besides being able to launch an oxygen intake through breathing exercises, yoga also reduce stress and prevent cardiovascular disease.

Actively engaged

As already mentioned, an inactive lifestyle to be one of the causes of cardiovascular disease. Theore, how to prevent it is to be actively engaged. For example, to get used to walking more often every day.

Quitting smoking

Smoking is not only bad for the lungs, but also the heart and blood circulation. So if you have a smoking habit, stop start now to prevent cardiovascular disease.

During pregnancy

Research never mentions that during pregnancy a woman who had suffered from pre-eclampsia or swelling of limbs doubled risk of cardiovascular disease. Thus arrived during pregnancy, pregnant women should be extra to maintain good health.

Understanding the symptoms

By understanding the symptoms, cardiovascular disease can be dealt with more quickly. Examples of symptoms of heart disease are pain in the chest area to the left arm and shoulder. In addition, pain in the back, neck, jaw until sometimes also be a symptom of cardiovascular disease in women.

Sun

Vitamin D is an important nutrient for the heart. So make sure you get vitamin D from the sun by sunbathing. Some foods can also be used as an alternative to meet the needs of vitamin D.

So many ways to prevent cardiovascular disease. Come live a healthy lifestyle fitness for your body!

High supplemental calcium intake may increase risk of cardiovascular disease death in men

A high intake of supplemental calcium appears to be associated with an increased risk of cardiovascular disease (CVD) death in men but not in women in a study of more 388,000 participants between the ages of 50 and 71 years, according to a report published Online First by JAMA Internal Medicine, a JAMA Network publication.

Calcium supplementation has become widely used, especially among the elderly population, because of its proposed bone health benefits. However, beyond calciums established role in the prevention and treatment of osteoporosis, its health effect on nonskeletal outcomes, including cardiovascular health, remains largely unknown and has become "increasingly contentious," the authors write in the study background.

Qian Xiao, Ph.D., of the National Cancer Institute, Bethesda, Md., and colleagues examined whether the intake of dietary and supplemental calcium was associated with mortality from total CVD, heart disease and cerebrovascular diseases. The study participants were 388,229 men and women ages 50 to 71 years from the National Institutes of Health-AARP Diet and Health Study in six states and two metropolitan areas from 1995 through 1996.

"In this large, prospective study we found that supplemental but not dietary calcium intake was associated with an increased CVD mortality in men but not in women," the authors conclude.

During an average 12 years of follow-up, 7,904 CVD deaths in men and 3,874 CVD deaths in women were identified and supplements containing calcium were used by 51 percent of men and 70 percent of women. Compared with non-supplement users, men with an intake of supplemental calcium of more than 1,000 mg/day had an increased risk of total CVD death (risk ratio [RR], 1.20), more specifically with heart disease (RR, 1.19), but not significantly with cerebrovascular disease death (RR, 1.14).

For women, supplemental calcium intake was not associated with CVD death, heart disease death or cerebrovascular disease death. Dietary calcium intake also was not associated with CVD death in men or women.

"Whether there is a sex difference in the cardiovascular effect of calcium supplement warrants further investigation. Given the extensive use of calcium supplement in the population, it is of great importance to assess the effect of supplemental calcium use beyond bone health," the authors conclude.
