A diagram explaining factors affecting arterial pressure. Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.
t. e. Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [11] High blood pressure usually does not cause symptoms itself. [1] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. [3] CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease ...
High blood pressure, also called hypertension, is a vicious and smart adversary.It’s vicious because it greatly increases the odds of heart disease and stroke, some of the leading causes of ...
Lightheadedness can be simply (and most commonly) an indication of a temporary shortage of blood or oxygen to the brain due to a drop in blood pressure, rapid dehydration from vomiting, diarrhea, or fever. Other causes are: altitude sickness, low blood sugar, hyperventilation, postural orthostatic tachycardia syndrome (increase in heart rate ...
Reflex syncope. Reflex syncope is a brief loss of consciousness due to a neurologically induced drop in blood pressure and/or a decrease in heart rate. [5][6][7][8][9][10][2] Before an affected person passes out, there may be sweating, a decreased ability to see, or ringing in the ears. [1] Occasionally, the person may twitch while unconscious. [1]
The Framingham Risk Score is a sex-specific algorithm used to estimate the 10-year cardiovascular risk of an individual. The Framingham Risk Score was first developed based on data obtained from the Framingham Heart Study, to estimate the 10-year risk of developing coronary heart disease. [1] In order to assess the 10-year cardiovascular ...
8.9 million (2015) [12] Coronary artery disease (CAD), also called coronary heart disease (CHD), ischemic heart disease (IHD), [13] myocardial ischemia, [14] or simply heart disease, involves the reduction of blood flow to the cardiac muscle due to build-up of atherosclerotic plaque in the arteries of the heart. [5][6][15] It is the most common ...
