Coronary Heart Disease
Coronary Heart Disease
Cardio-Vascular Disorders
Cardiovascular disorders include various heart diseases, vascular, and stroke disease. Many factors contribute to cardiovascular disorders, and these factors include atherosclerosis (gradual build of fat deposits in the blood vessels), makes the blood vessels become narrow, and the blood supply to the vital organs, for example, the brain is disturbed.Symptoms of cardiovascular disorders include; cyanosis, chest pain, dyspnea, swelling in the lower feet, irregular, skipping or, fluttering palpitation, easily fatigued, and decreased endurance, fainting, brief loss of consciousness, and dizziness.
The Pathophysiology of Cardiovascular Disorders
Infection or an injury can crest streaks of fat that adhere to the arterial wall, and block the proper blood flow into the heart or out of the heart. When the blockages rupture, they can lead to serious coronary problems, for example, heart attack.
Accumulation of plaque deposits on the arterial walls causes arteries to be inflamed. An increased level of C-reactive protein indicates of inflammation, hence responsible for the weakening of the arteries. Such inflammation can be reduced by medication, and the risks associated with it are also reduced.
Chronic endothelial injury occurs when fatty acid streaks and tissues of smooth muscles and connective tissue build up, or, a fibrous cap is formed inside the artery wall by extracellular lipid core. The chances of infection and cardiac disease are, therefore, increased by this. Radiography of the chest or chest echocardiography can reveal endothelial injuries present.
How Age Might Impact the Pathophysiology of Cardiovascular Disorders
The risks of developing a heart disease increase with age in both men and women. Therefore, older age I considered a risk factor. When women have not gone through menopause, they still have a high level of estrogen, which is thought to help in protecting against the heart diseases. Estrogen production drops as the woman grow old, and increases the chances of developing heart disease, though women develop heart disease later than men. The accumulation of fatty plaques is another factor. With age, there is a buildup of fatty plaques throughout the process of life. The blockages may get larger as a person grows old, and they may cause problems.
Dysrhythmia
Dysrhythmia is a condition which is characterized by variation in the regular heart beat. Some of the variations are normal, for instance, Annie’s palpitations, while others are problematic. During sleep, peoples heart slow down, but during exercise or emotion, they naturally speed up. Dysrhythmia associated with heart disease can be fatal.
The heart is organized machinery that is divided into four chambers, right and left atria at the top, and right, and left ventricle at the bottom. The beatings of the heart are kept in an organized manner. Sensation of an irregular heartbeat is termed as palpitation.
How Blood Pressure Can Contribute to Dysrhythmia
Blood pressure can lead to reduction of the heart’s ability to work for a very long time may result from ventricular fibrillation, and ventricular tachycardia, Blood that is not correctly pumped can cause damage to the heart, since the can form clots and break lose, and enter into the circulation, damaging the major organs.
The heart ability to pump blood is compromised if the blood pressure is abnormal; the heart beating too fast or too low, resulting in dysrhythmia.
