Main causes of hypertension and coronary heart diseases-
Modern living with its stresses and strains, mounting tension and pressure in everyday life, changes in the structure of the society and family leaving little cushion for an individual's problems and failures, changing dietary habits with city-folks often opting for time-saving high-calorie, high-fat, junk food, technological advancements such as easy modes of transport and machines, which leave little room for physical exercise, and machines, and increase in smoking and alcohol intake, all contribute to the problem.
Yet actually, not all the rise in incidence of coronary heart disease is real. Atherosclerosis, or narrowing of arteries by fat deposits, is also part of the normal aging process. With the increase in average life expectancy more people live to a ripe old age. This has caused a natural rise in the absolute number of patients. Also, more people, who would have been seen as having died of an unknown cause, are being diagnosed to have the disease, with greater awareness and better facilities of diagnosis. Several workers all over the world recognize that the "Modern Life Style" is closely linked with high blood pressure and Coronary Heart Disease (CHD). Today, at all ages and in all countries, diseases of the cardiovascular system is the major cause of death and disability.
Coronary heart disease that leads to heart attacks is the most important single cause of death in developed countries. It is said to be a disease largely of the middle-aged men. Congenital heart disease, Rheumatic heart disease, Cardiomyopathy, Cardiac pump failure secondary to back pressure from permanent damage to lungs due to smoking in the elderly are the other causes of cardiovascular disease.
There is a growing awareness about the need to look at alternative methods of management. It appears that the time is now ripe for mankind to look within for self-corrections to prevent and or cure these ailments.
How common is Hypertension?
Hypertension (high blood pressure) is not a disease in itself but its presence leads to an increased risk of developing some rather serious conditions later in life such as heart failure, heart attack and stroke.
Hypertension attacks nearly 40% of those above 45 years of age and mostly males. People who are over weight, who worry too much, have a lot of stress, who over work and even those who are lazy are susceptible for hypertension. In industrially developed countries hypertension is reaching epidemic proportions. A very high protein diet, overuse of alcohol and tobacco, lack of exercise, atmospheric pollution, too much of pressure of work, aggressive behavior etc., are some of the causes of hypertension.
What does the Blood Pressure depend upon?
These are-
Complaints due to hypertension
Most people think that high blood pressure results in symptoms like headache and dizziness; the truth is that unless it is extremely high it very rarely causes any of these problems. In most of the hypertensives there are no complaints and it gets detected on routine health checkup.
In some persons hypertension would be discovered after they complain to their doctor about the headache. This is possible because both headaches and high blood pressure are common but it does not mean that one is the cause of the other.
How to decide that the blood pressure is high?
In adults during rest, a systolic pressure under 140 mm Hg and a diastolic pressure under 90 mm Hg are normal. If the average of the blood pressure readings taken in quite surroundings on different occasions is above 140/90 mm Hg, the person is considered to be having high blood pressure.
So, does the reading 170/108 mm Hg indicate high blood pressure? No, not necessarily. Remember anxiety can raise the blood pressure and one common source of anxiety is having blood pressure measured.
What is low blood pressure?
In general lower the blood pressure for an otherwise normal healthy individual who can accomplish his daily routines and engage himself in physical exercise programs without any symptoms, the better the outcome for him in the long run. Hence, low blood pressure is not as worrying a problem as high blood pressure.
Management of hypertension
The diastolic blood pressure has to remain below 150/90 mm Hg. If the blood pressure remains below this level for some months on the same treatment and if you had one or two raised reading it is not necessary to rush for a change in things.
In cases, where mild hypertension is detected before it has done any harm, it is reasonable to try getting the blood pressure down without any drugs. If the person's diastolic blood pressure is above 100 mm Hg, in spite of all the non-drug methods, he may need to start drug treatment straight away.
And, about coronary heart diseases (associated with hypertension) - the recent data, available from cross-sectional surveys conducted on Indian populace, reveal a younger Indian age of onset of the disease (10 years younger than in the west). The prevalence of the disease in India has been estimated to be about 30 out of every 1000 people - a figure which, is as large as in the West. It is less common among women, perhaps, for hormonal reasons.
What are the effects due to CHD (Coronary Heart disease)?
When the oxygen supply to heart muscle reduces significantly, it produces pain in the chest. To begin with, whenever challenged, the heart transmits its anguish in the form of discomfort and sense of tightness over the middle of the chest. This is its way of telling, "Enough, I can bear no more." It often forces the person to stop what he is doing, and take rest. This is the well-known-known symptom of Angina Pectoris.
At times, the narrowed coronary artery may be completely blocked by a blood clot formed on its inner roughened wall. Or, a fatty plaque or clot detached from an upper, larger artery may travel to its narrower branch, suddenly cutting off its blood flow. When this happens and a coronary artery or its branch suffers a shutdown, the portion of the heart muscle it feeds gets damaged. How serious the damage would be depends on the size and position of the plugged vessel. The larger the affected vessel, and less the supply to that area from other neighbouring arteries (which may have sprung up if the process had been gradual), the greater is the damage suffered by the heart. This is called Heart attack.
Functions of Heart
A) What is Cardiac output?
The volume of blood that is pumped out of the heart per unit time is called the Cardiac Output. This depends upon the force and rate of contraction of the heart. In a normal adult man, while lying down the average cardiac output is 5.5 liters/minute.
The force with which the heart contracts depends on the extent to which the muscle is stretched to begin with. The more the ventricle is filled, the greater is the initial stretch. Filling is dependent on the venous return, i.e. the amount of blood that returns to the heart, via the veins. This depends on two factors, namely the position of the body and pumping action of the calf muscles. Standing decreases cardiac output as the venous blood returning from the legs to the heart is reduced. Conversely, lying down increases the venous return. While walking, the contraction of the calf muscles facilitates the venous return of the blood from the legs.
The other factor that influences the Cardiac Output is the rate and force of contraction of the heart, which in turn is influenced by its innervation. Sympathetic nerves increase both the heart rate, and force of contraction, thus increasing the cardiac output. In contrast, parasympathetic nerves reduce the cardiac output by reducing both the rate, and force of left ventricular contraction.
B) How is Blood Pressure built up?
Circulating blood presses against the walls of the blood vessels with a force (pressure). Blood pressure is the force (or pressure) with which the heart pumps blood through the arteries and so allows the blood to reach various parts of the body. The pressure is greatest during systole, when the heart contracts and forces blood into the arteries of the body. This is known as systolic blood pressure. The pressure is lower during the relaxation phase of the heart and this is referred to as the diastolic blood pressure. The blood pressure that is recorded at the arm by the use of a clinical blood pressure apparatus is the pressure that is felt against the walls of the artery in the upper arm. The normal resting blood pressure in an adult male (20-50 yrs.) as recorded in the arm is about 90 to 140 mm of mercury (mm of Hg) during the systolic phrase and 60 to 90 mm of Hg during the diastolic phase. The average is considered to be 120/80 mm of Hg. Without this pressure the blood would not be able to supply the body with the necessary oxygen and food. It varies from time to time depending on the level of physical and mental activity. It is lower during rest and increases with tension. It also varies from person to person.
The relation between Diet, Cholesterol and Heart
We know that both hypertension and CHD (Coronary Heart Disease) are related to modern lifestyle with a background of family history. Dietary factors must rank as the first consideration in the management of heart problems. The role of dietary fats in the heart disease has been recognized over the last 4 to 5 decades. Many studies which have looked at mortality and the development of certain diseases in primitive and rich communities throughout the world have shown that the deaths from coronary heart disease, associated with hypertension, appear to increase with higher intakes of saturated fats. At the same time, these are associated with high blood cholesterol levels; the higher the diet is in animal-derived fats, the higher the blood cholesterol level. High blood cholesterol in turn appears to be a factor in inducing fatty deposits in blood vessels which we have seen is an important contributory factor in inducing atheroma and high blood pressure.
What kind of diet causes heart disease?
Excessive of total calories, animal fats, dairy and other saturated fat products, sugar, and a low fibre-content diet are all closely linked to coronary artery disease.
Animal fats- meat, eggs, and milk products- are the most culpable, as they have a high cholesterol and saturated fat content in them. They raise the blood cholesterol levels and contribute to obesity. The triglyceride levels are more sensitive to total caloric balance and alcohol intake. Much against the common belief, physical activity, emotional stress, smoking, and intake of coffee or tea have only weak or indirect influences on cholesterol and triglyceride concentration.
In what way does Yoga help in the management of Hypertension and CHD (Coronary Heart Disease)?
Since 1960s the researchers have shown (through short term and long term controlled studies) the beneficial effects of individual practices of yoga such as Savasana or Pranayama or meditation, practiced regularly for 20 to 30 minutes per day to reduce the blood pressure significantly in mild and labile hypertension. When it comes to moderate or severe essential hypertension or CHD, the problem which was psychosomatic in nature seems to have moved on several steps ahead to cause organic changes resulting in coronary blockage (CHD) or permanent changes of arteries (hypertension). Hence yoga practices for 30 to 60 minutes in 24 hours without a total change in the approaches and attitudes may not correct the cardiac problems. Realizing this, lifestyle change programmes have been advocated with remarkable changes in the state of health. The degree of blocks in the coronaries have reduced significantly after one year of lifestyle change programs.

How to Do?
Stand straight with arms by the side of your body.
Gently bend your right knee and place the right foot high up on your left thigh. The sole of the foot should be placed flat and firmly near the root of the thigh.
Keep your left leg is straight. Find your balance.
Once you feel well balanced, take a deep breath in, gracefully raise your arms over your head from the side, and bring your palms together in hands-folded position(‘Namaste’ mudra).
Look straight ahead in front of you, at a distant object. A steady gaze helps maintain a steady balance.
Make sure that your spine is straight. Your entire body should be taut, like a stretched elastic band. Keep taking in long deep breaths. With each exhalation, relax the body more and more. Just be with the body and the breath with a gentle smile on your face.
With slow exhalation, gently bring down your hands from the sides. You may gently release the right leg.
Now, stand tall and straight as you did at the beginning of the posture. And repeat this posture with the left leg off the ground on the right thigh.
