Cardiovascular Disease and Hypertension
Across the globe, there are over 970 million individuals who have increased blood pressure. The stats signify it to be a widespread problem; but, the ratio tends to differ from place to place. According to the stats, there are 330 and 640 million people with hypertension in developed and developing countries respectively. Hypertension is attributed as one of the major underlying causes of premature death across the globe, states the World Health Organization (WHO), as the figures continue to increase over the time. According to the estimation, there will be 1.56 billion adults with high blood pressure by 2025.
When Is It A High Blood Pressure?
140 mm Hg/ 90 mmHg systolic and diastolic blood pressure or above is considered high blood pressure. The systolic and diastolic blood pressures are the maximum and minimum pressures observed in the arteries during the contraction of the heart.
Impact of Hypertension on Blood Vessels and the Heart
Strokes and coronary heart related diseases are usually caused due to hypertension. 50% of the hemorrhagic and ischemic strokes are a result of hypertension.
The blood vessels weaken or clog due to hypertension produced stress. The narrowed blood vessels can block fatty material decomposition and cause blood clots along the lining of the blood vessel wall. Cardiovascular diseases are common among the 50 years or less old group due to hypertension. The cardiovascular risks tend to increase with aging; hence, you need to be careful!
Few of the sustaining measures of lowering the blood pressure levels include physical activeness, less salt consumption and obesity prevention. High salt consumption augments the chances of falling prey to cardiovascular diseases and increased blood pressure levels.
Hypertension- The Types:
Pumping action of the heart, the amount of pumped blood, the condition and size of the arteries are the blood pressure determining factors. The other deciding factors include hormonal levels and kidney functioning.
The cause of hypertension is vague in some cases. Hypertension appears to be a common disease amongst the younger generation. In the United States and several other countries, it is known be a cause for long-term health risks among teenagers.
Cardiac output and vascular resistance determine BP. The absence of reparation and fluctuation in any two of the variables increases the pressure.
The following listed factors impinge the heart’s output:
- Sympathetic nerve syndrome
- Extracellular volume
- Effective circulation volume- mineralocorticoids, angiotensin and atrial natriuretic hormones
Cardio Vascular resistance is regulated through the following factors:
- Depressors- prostaglandin I 2, kinins, atrial natriuretic hormones and endothelial relaxing factors.
- Pressors – vasopressin, catecholamines, calcium (intracellular), sympathetic nervous system and angiotensin II
Hypertension is a chronic medical illness which demands changes in the eating habits as well. However, through medications, the chances of life expectancy can be increased. May 17 is widely celebrated as World Hypertension Day. On this day, the symptoms, precautions, and treatments are inculcated.
