Dangers of hypertension

Dangers of hypertension
Hypertension is often called. Silent killer. Because it does not produce obvious symptoms before the body has a serious injury. Hypertension if not controlled, it will damage the heart, arteries, kidney and brain. Eyes are also very sensitive to the effects of hypertension. Daily high pressure fluctuations (that is, the blood pressure during the day to be higher than in the evening) are more likely to have other health problems due to high blood pressure.
Studies have shown that people with high blood pressure and without control are about 3 times more likely to have coronary heart disease than those with a normal blood pressure, and 6 times more likely to have congestive heart failure, and 7 times more likely to have a stroke. However, the adverse effects of the discussion in this chapter are not inevitable. You can control your blood pressure by working closely with your doctor to prevent any health problems associated with hypertension.
Heart
As an organ that pumps blood to the body, the heart needs to work too much in order to fight blood vessels in order to fight the blood vessels. Like any muscle, when the heart is forced to work harder, the volume of the heart will become larger. The cardiac muscle wall becomes thicker and shorter, and the muscle loses its original elasticity. However, after the heart is enlarged, it is usually not enough to supply a blood supply with oxygen and nutrients. Also the heart increased and then also more easily produce irregular heartbeat. This is called arrhythmias, feel the heartbeat when less.
Left ventricular hypertrophy occurs when the largest Chamber of the heart – the left ventricle is abnormally dilated. As the wall of the ventricle becomes thick, the ventricles become harder to pump blood, which is filled with blood. Pump out of the blood less and less, resulting in breathing difficulties, angina (chest pain), heart palpitations and dizziness. Blood may flow back to the blood vessels in the lungs, causing greater pressure and causing a rapid breathing. If this process continues, and the pressure is very high, it will occur in the case of pulmonary edema, that is, pulmonary water. Pulmonary edema can lead to severe respiratory disease, which belongs to the emergency, if not treated in time may be fatal.
If hypertension is not controlled, the heart function will begin to weaken after many years. When this happens, the blood flow back into the lungs, which makes you feel like you’re in a state of congestion. The weak heart is unable to maintain blood circulation, thereby causing other parts of the body muscles will become weak from severe hypoxia, so it will happen congestive heart failure. People with congestive heart failure in the early stage of the disease has a respiratory problems, development to the late stage of patients with respiratory symptoms. When sitting upright, breathing becomes easier. In addition, there are some groups also have water. This is called edema, edema will cause legs because of too much water and swelling.
In a large study, which began in late 1940s, the Fleming Han heart research program, doctors found that about 40% of men and 60% of women in the case of congestive heart failure were caused by high blood pressure. In patients with congestive heart failure in the study, about 91% of people with hypertension, previously. Men with high blood pressure, the risk of congestive heart failure is about 2 times the normal blood pressure, and women with high blood pressure, the risk of congestive heart failure is about 3 times the normal people. Men with congestive heart failure, only less than 1/4 of people in the disease was diagnosed, the survival of more than 5 years, the survival rate of female patients is less than 1/3.
A coronary artery that supplies oxygen and energy to the heart is also affected by high blood pressure. When coronary artery is not for heart patients provide sufficient oxygen, patients in forced breathing will feel to pain, tightness or our Europe of tightness in the chest, this is angina pectoris. Like congestive heart failure, angina pectoris, early in the disease can feel, and then will be more frequent episodes, even at rest or is in the mood change commanded will occur.

Simple angina does not damage the heart, but it can be a warning sign of a heart attack (see chart below). A heart attack, the pain duration is longer than angina, and usually accompanied by other symptoms, such as nausea and sweating. In the heart attack, because of obstruction in the coronary artery, leading to the local heart blood supply is cut off, and then make this site due to the lack of blood supply and lead to cardiac death. If a large part of the heart is out of blood supply, the heart will stop unless it provides first aid.
Left ventricular hypertrophy can cause angina pectoris. Thickening of the left ventricular muscle will always pressure small blood vessels, small blood vessels were completely flattened until. The results will be caused by the small blood vessels to nourish the organization in a short period of time, thus causing the heart to angina. If hypertension is not always controlled, the left ventricular hypertrophy will further develop into myocardial atrophy (tissue death due to vascular damage), resulting in the loss of part of the heart pump blood function. When the heart can’t promote blood circulation to the body, it will lead to congestive heart failure.
