Cardiovascular diseases: Types, symptoms, treatment, CVD- Cardiovascular disease are a group of disease of the heart and vascular system.
The major conditions are ischaemic heart disease and cerebrovascular disease (stroke).
Rheumatic heart disease continues to be a serious health problem in many developing countries.
In countries, where life expectancy is more than 60 years, these are the leading cause of mortality.
These are more prevalent in the urban areas than in rural areas reflecting several risk factors.
It including sedentary lifestyles, consumption of fatty foods, obesity and smoking.
There is growing evidence to show that these pose a serious health threat to poor segments of the population.
People in the developing countries are particularly susceptible to changes in lifestyles and environment, resulting in relatively higher morbidity and premature death rates than in other countries.
Cardiovascular Disease (CVD)
It includes dysfunctional conditions of the heart, arteries.
Veins that supply oxygen to vital life-sustaining areas of the body like brain, the heart itself, and other vital organs.
Without oxygen, the tissue or organ would die.
High Blood Pressure (hypertension) often results from this excess fat or plaque buildup because of the extra effort it takes to circulate blood.
Even though the heart works harder, blockages still shortchange the needed blood supply to all areas of the body.
The body’s amazing survival systems will mask the subtle damage that is occurring from this extra wear and tear, but not forever.
High blood pressure is called ‘The Silent Killer’ because the first warring sign is an angina attack or a deadly heart attack or a stroke.
Kidney disorders (which leave extra fluids, sodium, and toxins in the body), obesity, diabetes, birth control pills, pregnancy, smoking, excess alcohol, stress, and thyroid and adrenal gland problems can also cause and exacerbate a high blood pressure condition.
Proper ranges of cholesterol are also important in the prevention of heart attack or stroke.
Cholesterol is not actually a damage mechanism but is more an indicator of compromised liver function, and increased risk of heart attack.
A number of health-related behaviours practiced by people contribute markedly to cardiovascular disease everyday.
Excessive use of tobacco, sedentary life styles and bad nutritional habits are the main causes of cardiovascular diseases.
Types of cardiovascular disease
Coronary artery disease
Damage or disease in the heart’s major blood vessels.
High blood pressure
A condition in which the force of the blood against the artery walls is too high.
Sudden, unexpected loss of heart function, breathing and consciousness.
Congestive heart faliure
A chronic condition in which the heart doesn’t pump blood as well as it should.
Improper beating of the heart, whether irregular, too fast or too slow.
Damage to the brain from interruption of its blood supply.
