Coronary Artery Disease
NIH - Medical Encyclopedia Coronary heart disease "Coronary heart disease (CHD) is a narrowing of the small blood vessels that supply blood and oxygen to the heart. CHD is also called coronary artery disease. Coronary heart disease is usually caused by a condition called atherosclerosis, which occurs when fatty material and a substance called plaque builds up on the walls of your arteries. This causes them to get narrow. As the coronary arteries narrow, blood flow to the heart can slow down or stop, causing chest pain (stable angina), shortness of breath, heart attack, and other symptoms. Coronary heart disease (CHD) is the leading cause of death in the United States for men and women. … Chest pain or discomfort (angina) is the most common symptom. You feel this pain when the heart is not getting enough blood or oxygen. How bad the pain is varies from person to person.
There are two main types of chest pain:
• Atypical chest pain -- often sharp and comes and goes. You can feel it in your left chest, abdomen, back, or arm. It is unrelated to exercise and not relieved by rest or a medicine called nitroglycerin. Atypical chest pain is more common in women.
• Typical chest pain -- feels heavy or like someone is squeezing you. You feel it under your breast bone (sternum). The pain usually occurs with activity or emotion, and goes away with rest or a medicine called nitroglycerin. Adults with typical chest pain have a higher risk of CHD than those with atypical chest pain.
Other symptoms include: • Shortness of breath • Heart attack -- in some cases, the first sign of CHD is a heart attack…
Tips for preventing CHD or lowering your risk of the disease: • Avoid or reduce stress as best as you can. • Don't smoke. • Eat well-balanced meals that are low in fat and cholesterol and include several daily servings of fruits and vegetables. • Get regular exercise. If your weight is considered normal, get at least 30 minutes of exercise every day. If you are overweight or obese, experts say you should get 60 to 90 minutes of exercise every day. • Keep your blood pressure, blood sugar, and cholesterol under control"
NHS – Coronary Heart Disease (Videos) “The main symptom of coronary heart disease is angina. Angina can be a mild, uncomfortable feeling similar to indigestion. In severe cases, it causes a feeling of extreme pressure on the chest, breathlessness, trapped air and belching. It is usually triggered by physical exercise or stressful situations, and tends to go away when you stop what you're doing, when you rest or when you take medication. Other symptoms include: Heart palpitations When you become aware of your heart beating irregularly or harder than normal. Heart attack If your arteries become completely blocked, you will have a heart attack. … Heart failure Heart failure occurs when the heart gradually gets too weak to pump blood around the body. This can cause fluid to build up in the lungs, making it increasingly difficult to breathe. Heart failure can happen suddenly (acute heart failure) or over a period of time (chronic heart failure).”Highlighted Articles
Positive and negative affect and risk of coronary heart disease: Whitehall II prospective cohort study. (BMJ. 2008) “Smoking, hypertension, hypercholesterolaemia, and diabetes are established risk factors for coronary heart disease, a leading cause of morbidity and mortality in Western industrialised countries.1 2 However, psychological factors, such as emotions, may also have a role in the development of coronary heart disease.3 4 Several prospective studies have found anxiety, hostility/anger, and depression to be associated with an increased risk of coronary heart disease in healthy participants.3 5 As the relative importance of these three negative emotions on risk of coronary heart disease remains largely undefined,6 7 they have been hypothesised to be the components of a single underlying factor, labelled negative affect. Negative affect refers to “stable and pervasive individual differences in mood and self-concept characterised by a general disposition to experience a variety of aversive emotional states.”5 8 High negative affect has been described as a general tendency to report “distress, discomfort, dissatisfaction, and feelings of hopelessness over time and regardless of the situation,” and low negative affect is characterised by “calmness and serenity.”8 9 Supporting this conceptualisation, a considerable neurobiological and psychological overlap between anxiety, hostility/anger, and depression has previously been shown.10 11 As attempts to link psychological factors to heart disease have focused on negative emotions, mostly depression,7 whether positive emotions might also have a role in the development of coronary heart disease remains unclear.“
[Heart disease and stroke] (Tidsskr Nor Laegeforen. 2007)"Most cases of heart disease and stroke are caused by atherosclerosis, and the two diseases have much in common with regards to risk factors, treatment and prognosis. Heart disease may also be a direct cause of stroke. About one in four cerebral infarctions are due to embolism from the heart to the brain, mainly because of atrial fibrillation, but also because of diseases such as acute myocardial infarction, dilated cardiomyopathy and prosthetic heart valves (cardioembolic stroke). Stroke can also be caused by a cardiogenic fall in blood pressure in patients with stenoses in pre- or intracerebral arteries (haemodynamic stroke). Patients with symptoms of atherosclerosis in one artery system should be treated as if they have a high risk of developing symptoms from other artery systems. The possibility of a cardiac embolic source should always be considered in patients with acute brain infarctions."
Optimal Medical Therapy with or without PCI for Stable Coronary Disease (NEJM 2007) "Background In patients with stable coronary artery disease, it remains unclear whether an initial management strategy of percutaneous coronary intervention (PCI) with intensive pharmacologic therapy and lifestyle intervention (optimal medical therapy) is superior to optimal medical therapy alone in reducing the risk of cardiovascular events. … Conclusions As an initial management strategy in patients with stable coronary artery disease, PCI did not reduce the risk of death, myocardial infarction, or other major cardiovascular events when added to optimal medical therapy."

Jump in Resting Heart Rate Might Signal Higher Death Risk “People whose heart rates increased from under 70 beats per minute to more than 85 beats per minute over 10 years had a 90 percent increased risk of dying from heart disease compared to people whose heart rates stayed around 70 beats per minute, according to the large study.” "Resting heart rate is one of the simplest measures in medicine and everyone can do that by themselves at home. From cross-sectional studies, it is known that a person's resting heart rate is related to the relative risk of premature cardiovascular disease and death. However, it has not, before now, been associated with an increased risk of premature cardiovascular death," said study senior author Ulrik Wisloff, director of the K.G. Jebsen Center of Exercise in Medicine in Trondheim, Norway. "Our observations suggest that resting heart rate may be an important prognostic marker for ischemic heart disease and total mortality," said Wisloff, who added that changes in resting heart rate may signal the need for lifestyle changes.”
U-Shaped Curve for Sleep Duration and Cardiovascular Disease “They conclude that people reporting consistently sleeping five hours or less per night should be regarded as a higher-risk group for cardiovascular morbidity and mortality. And that sleeping nine hours or more per night may represent a useful diagnostic tool for detecting subclinical or undiagnosed comorbidity.”
Heart Disease: What Are the Medical Costs? “What are the costs per person? One study estimated that over the course of a person's lifetime, the cost of severe coronary artery disease -- the most common form of heart disease -- is more than $1 million. That includes both direct and indirect costs.”
