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.
