As mentioned before, CAD is caused by the unwanted build-up of plaque within the walls of the coronary arteries which leads to restriction of blood flow to the heart (Mayo Clinic, 2017). Risk factors that are associated with increasing one’s chance of developing CAD are high cholesterol, smoking, high blood pressure, diabetes/obesity, sedentary lifestyle, high stress, and family history (Mayo Clinic, 2017). There are two forms of cholesterol that travel within the blood: HDL (High-Density Lipoprotein) known as the good cholesterol and LDL (Low-Density Lipoprotein) known as the bad cholesterol. High cholesterol is correlated with high levels of LDL cholesterol and low levels of HDL cholesterol. The reason high cholesterol levels increase …show more content…
Hypertension is defined as the amount of pressure blood flow exerts into the arteries. This becomes a problem because hypertension ultimately puts an added force against the walls of the arteries making them more susceptible to not only narrowing of the artery walls but to plaque build-up as well. The added force associated with hypertension also begins to diminish the elasticity and strength of the artery walls which limits the amount of blood flow that can reach the myocardium.
Type 2 Diabetes which is a direct cause of obesity is known to increase the chances of one developing CAD. Type 2 diabetes is correlated with high glucose levels due to insulin resistance. The hormone Insulin converts glucose into glycogen which is stored in the liver and is later used as fuel by the body. With insulin resistance, one’s body does not respond well to the hormone, so the body continues to produce more and more insulin without storing glucose as glycogen within the liver. This leads to an increased level of glucose in the bloodstream which can become an issue. Elevated glucose levels can lead to a decrease in the amount of HDL within the bloodstream leading to elevated levels of LDL within the bloodstream (Health line, 2015). The increase of LDL cholesterol within the bloodstream leads to the build-up of cholesterol within the coronary arteries
Coronary artery disease (CAD) develops when plaque builds up in the narrow arteries of the heart. The arteries that are affected supply blood to your heart, oxygen, and numerous amounts of nutrients to the heart. The plaque that builds in the arteries is from the amount of cholesterol that is accumulated in the arteries. The plaque that builds within the arteries of the heart decrease the blood flow to the heart often resulting in chest pain (angina), shortness of breath, or other symptoms. This disease is often not diagnosed until the patient has a heart attack. The reason that coronary artery disease goes unnoticed is because this disease develops over decades. “Heart disease is the leading cause of
Dyslipidemia is a comorbidity in diabetes. Free relationship between hoisted triglycerides (TG), cardiovascular (CV) and mortality is to a great extent begging to be proven wrong. Lifted TG is associated with high thickness lipoprotein (HDL), low thickness lipoprotein (LDL) and different lipoproteins. Hypertriglyceridemia is connected with impressively expanded long haul mortality and cardiovascular danger. Relationships between's lower HDL cholesterol prompted contemplates prescribing that HDL qualities could be refered to as more probable benefactors to chance than the TG themselves. Grouping of hoisted TG as a noteworthy CV hazard component is thusly imperative since it manages whether high TG ought to be an objective for treatment. Sort 2 diabetes is classified by both insulin resistance and hyperinsulinemia. In hyperlipidemia patients, free unsaturated fats go about as forerunners to glycogenesis in the liver, in this manner expanding apoptosis in beta cells of the pancreas and expanding insulin resistance in muscles. This along these lines results in diminished insulin emission and tenacious hyperglycemia.
Hypertension (HTN) is a chronic cardiovascular condition that is characterized by high blood pressure. The blood pressure commonly abbreviated as BP is a measure of the force exerted on the blood vessels as the blood passes through them. The amount of blood pumped and the narrowness of ones’ vessels are directly proportional to the blood pressure (Mayoclinic staff, 2014).
High cholesterol is a dangerous disease that can lead to many life-threatening ailments, and can be lowered by eating healthy, while maintaining a balanced diet of leveled cholesterol. Cholesterol, the sleek-fat like substance that roams in the blood of a body. It is vital to life, but when there is too much intake of cholesterol, it can cause the body to malfunction and cause problems. There are two types of cholesterol HDL and LDL, which varies in the amount of protein and cholesterol it holds Too much cholesterol in a body is dangerous, and surprisingly, has no symptoms. The two main types of cholesterol are HDL and LDL, HDL helps reduce the chances of chronic heart disease, whereas LDL is the main reason for plaque build-up in artery
High blood pressure (hypertension ) is defined as high pressure (tension ) in the arteries , which are the vessels that carry blood from the heart to the rest of the body . High blood pressure is considered one of the highest causes of morbidity , one of the main leading causes of cardiovascular disease , and social global burden health risk factor . In addition to the high-cost burden to the global health service providers . About 70 million American adults have high blood pressure . Only about half of people with high blood pressure have their condition under control . Nearly 1 of 3 American adults has prehypertension , blood pressure numbers that are higher than normal , but not yet in the high blood pressure range . High blood pressure
The plaque restricts blood flow to the heart and deprive the heart of oxygen it needs to function properly. CAD can be chronic, which is narrowing of the coronary artery and limitation of the blood supply to part of the muscle, or it can be acute, which results from a sudden plaque that ruptures. According to Warnica (2013), rupturing of the plaque “exposes collagen and other thrombogenic material, which activates platelets and the coagulation cascade, resulting in an acute thrombus, which interrupts coronary blood flow and causes some degree of myocardial ischemia.” The major risk factors that can lead to atherosclerosis and coronary artery disease are hypertension, dyslipidemia, tobacco smoking, diabetes mellitus, obesity, sedentary lifestyle, and genetic predisposition. The risk factors present in M.T.’s life are history of angina pectoris, history of uncontrolled hypertension due to non-compliance with treatment, obesity, and stress. M.T. is overweight with 289 pounds. M.T.’s cholesterol level is high at 280mg/dl. M.T.’s stress is related to experiencing the death of his best friend and business partner from cancer. Having three teenage children who are constantly in trouble at school and a wife who recently lost her job can be a stress factor in M.T.’s
Many people find out about hypertension only when they suffer a heart attack or get a medical check-up done. Hypertension is a life-threatening condition characterized by high blood pressure in the arteries leading to the lungs and heart. Unlike regular hypertension or high blood pressure, hypertension occurs when the arteries in the lungs become blocked or narrow, making it harder for the heart to pump blood through them. This raises blood pressure in the lungs and causes the heart to weaken, which may eventually lead to heart failure. Hypertension is also dangerous because it can lead to strokes, heart attacks, heart failure, or kidney disease. So the goal of hypertension treatment is to lower high blood pressure and protect important organs, like the brain, heart, and kidneys from damage.
CAD is an artery disease where the blood vessels that supply blood to the heart becomes hardened or narrowed due to the build-up of cholesterol and plaque in the inner wall; this causes a reduced blood flow to the heart muscles. Hence, if the arteries become severely narrowed or blocked, the heart becomes deficient for nutrients and oxygen.
The heart pumps blood into the arteries and the force of the blood pushing against blood vessel walls is called blood pressure. Arteries carry the blood throughout the body. High blood pressure is also know as hypertension and is very dangerous in many different ways. One way is that it makes the heart have to work harder in order to pump the blood to the body. Secondly it contributes to hardening of the arteries and lastly, it also contributes to heart failure. A healthy heart is essential to life and having high blood pressure it not healthy for the heart. It has been proven that there are many different causes that have been linked to high blood pressure.
Cholesterol can lead up to coronary heart disease. This is where deposits of lipids cause plaque build-up restricting the blood flow to the heart which
Some risks for CAD could be smoking, HTN, obesity, bad cholesterol, diabetes, and genetics. There are so many risk factors for CAD, but most of them can be lowered by changing one’s lifestyle. Usually, up till the age of 70, males may have a higher chance for CAD.
Hypertension is a chronic medical condition in which the blood pressure in the arteries is elevated. Blood pressure is summarized in by two measurements, systolic and diastolic, which depend on whether the heart is muscle is contracting (systole) or relaxed between beats (diastole). Normal blood pressure at rest is within the range of 100-140mmHg systolic (top reading) and 60-90mmHg diastolic (bottom reading). High blood pressure is said to present if it is often at or above 140/90 mmHg. For most cases of mild to moderate hypertension there are no symptoms. The condition has
CAD is when the heart is subjected to a reduction in blood flow that negatively affects its ability to pump (McCance & Huether, 2014). The leading cause of CAD is atherosclerosis (Porter & Kaplan, 2011). Atherosclerosis is when fatty deposits, known as atheromas, deposit between the tunica intima and tunica media of medium and large coronary arteries (Porter & Kaplan, 2011). Macrophages and inflammatory cytokines detect the injury to arterial lining and attempt to protect the body by engulfing it and covering with fibroblasts and collagen (McCance & Huether, 2014). This results in the formation of an atherosclerotic plaque. As time passes the atherosclerotic plaque increases in size and causes complete or partial occlusion of a coronary artery
Coronary Artery Disease is a condition where the blood flow through the coronary arteries of the heart become partially or completely blocked by plaque buildup. CAD is responsible for over 500,000 deaths in the USA annually. Unfortunately in ¼ of the population, death is the first warning sign of CAD. Atherosclerosis is the process by which plaque builds up in the vessels that supply blood and oxygen to the heart muscle. This lack of blood flow is called ischemia, which will lead to angina in many cases. Angina is caused by a lack of perfusion of the myocardium. CAD is a disease that is developed over time due to unchanged risk factors such as obesity, sedentary lifestyle, hyperlipidemia , cigarette smoking, and hyperlipidemia. The severity of Coronary Artery Disease can be managed through lifestyle changes and medication. If the disease has advanced beyond natural repair by lifestyle modifications, surgery may be the next option. Coronary Artery Bypass Graft (CABG) surgery or placement of cardiac stents are the two most common forms of surgery to fix CAD. These surgeries are not a substitute for lifestyle modifications, but may help those with severe CAD begin to make lifestyle changes without symptoms arising at low intensity exercises.
Hypertension is defined a consistent elevation of the systolic blood pressure above 140mmHg, a diastolic pressure above 90mmHg or a report of taking antihypertensive medication. Early diagnosis and effective management of hypertension is essential because it is a major modifiable risk factor to cerebrovascular, cardiac, vascular, and renal diseases. The higher the blood pressure, the greater the risk for heart attack, heart failure, stroke, and kidney disease.
