❤️ HEART DISEASE
🫀 Understanding Coronary Heart Disease
Coronary heart disease refers to illnesses that result from the narrowing and blocking of the coronary arteries, which enmesh the heart and supply it with oxygen-rich blood. 🩸 As we know, blood vessels become narrowed as plaque builds up in the condition called atherosclerosis. Blockage can occur if a clot of plaque or blood platelets develops and gets lodged in an artery, preventing blood flow. 🚫
Brief reductions of oxygenated blood to the heart can produce painful cramps, called angina pectoris, 😣 in the chest and arm, back, or neck. This is most likely during exercise or stress, 🏃♂️😰 and little or no permanent damage occurs if the blockage ends quickly. But if reduced blood supply is severe or prolonged, part of the muscle tissue of the heart (myocardium) may be destroyed—a condition called Myocardial Infarction, or heart attack. 💔
⚠️ Common Symptoms of a Heart Attack
Many victims delay going to the hospital for hours because they don't know the symptoms of a heart attack. 🏥 The following are common symptoms of a heart attack: 🚨
- Uncomfortable pressure, fullness, squeezing, or pain in the center of the chest 💢 that lasts for more than a few minutes.
- Pain spreading to the shoulders, neck, or arms. 💪😖
- Chest discomfort with lightheadedness, fainting, sweating, nausea, or shortness of breath. 😵💦😮💨
Not all of these symptoms always happen in a heart attack—if some start to occur, the person should get medical care immediately. ⏰🚑 Prompt treatment can often prevent serious myocardial damage.
🫁 Congestive Heart Failure
Many people with heart disease develop Congestive Heart Failure, which has three permanent features:
- The heart is enlarged, 🫀📈
- The pumping capacity is reduced, 📉
- The person becomes short of breath with little exertion. 😮💨
📊 Prevalence and Prognosis
Heart disease is prevalent in developed countries. 🌍 In the United States, each year about 1.1 million Americans suffer a heart attack; more than a third of the victims die, 💀 usually before they reach a hospital. About half of heart attack victims take 2 hours or longer to get medical help. ⏳
The prognosis for a patient after a myocardial infarction depends on several factors, especially the extent of arterial damage and the condition of the heart's ventricles. 🔍
🎯 Who is at Risk of Heart Disease and Why?
Several demographic, lifestyle, and physiological characteristics are associated with developing heart disease. 📋
📅 Age, Gender and Sociocultural Risk Factors
The prevalence rates for heart disease increase as people get older, 👴 particularly after about 45 years of age. In the years prior to old age, far more men than women ♂️ develop and die from heart disease. Even though women are less likely than men to have heart attacks, they are more likely to die from them if they have them. 💔
The link between heart disease and sociocultural factors can be seen in the death rate data for different ethnic groups in the United States: 🇺🇸 Among both men and women, heart disease death rates are two to three times higher for blacks ⬛ than for Asian Americans, with the rates for whites, Native Americans, and Hispanics being intermediate. Interestingly, a study of death rates around 1990 in New York City 🗽 revealed that blacks who were born in the Southern United States had far higher mortality rates from cardiovascular disease than those born in the North, whose death rates were similar to those of whites. And cross-cultural research has found that men and women in Russia 🇷🇺 have extremely high death rates from cardiovascular disease, while the French 🇫🇷 and Japanese 🇯🇵 have very low rates. These findings suggest an important role of lifestyle in heart disease. 🏃♂️🥗
🏃♀️ Lifestyle and Biological Risk Factors
Part of the reason for age, sex, and sociocultural differences in risk of heart disease lies in biological and lifestyle variations. 🧬 For example, hypertension—the condition of having high blood pressure consistently over an extended period of time—is a major risk factor for heart disease. 🩺 Nearly one-fourth of adult Americans are hypertensive. High blood pressure has no overt symptoms, but its presence indicates that the heart is working harder than normal. 💪 When this continues over a long period of time, the heart becomes enlarged and has more and more difficulty meeting the demands of the body. High blood pressure also increases the development of atherosclerosis, causing blood vessels to become narrowed and less elastic. 🚫 This increases the risk of a blood clot or piece of plaque becoming lodged in an artery and causing a myocardial infarction. 💥
Several other lifestyle and biological risk factors are important in heart disease. They include: 📋
- 👨👩👧👦 Family history of heart disease
- 🚬 Cigarette smoking
- 🩺 High blood pressure
- 🩸 High LDL and low HDL cholesterol levels
- 🛋️ Physical inactivity
- 🩸💉 Diabetes
- ⚖️ Obesity
- 😰 Stress
People who stop smoking and reduce their cholesterol intake and blood pressure have half the risk of dying of heart disease. ✅💪 As we saw in our earlier lectures, stress plays an important role in the development of heart disease, particularly through its connection to the Type A behavior pattern and hypertension. 😤 Chronic stress, anger, and hostility appear to contribute to people's high blood pressure. 😠📈
😡 Negative Emotions and Heart Disease
Prospective studies have shown that men and women who experience chronic high levels of hostility, depression, or anxiety 😰😞😠 are more likely than others to develop heart disease and hypertension. The link between negative emotions and heart disease involves two avenues:
- Lifestyle factors 🍔🚬—People tend to have less healthful lifestyles when they experience negative emotions.
- Physiological effects 🧬—Negative emotions have physiological effects that promote heart disease.
Some of the clearest physiological links have been shown among people with the Type A behavior pattern. ⚡ When in stressful situations, Type A individuals—particularly those who experience frequent high levels of anger and hostility—often show high physiological reactivity, 📈 which includes increased blood pressure, catecholamine, and corticosteroid levels. Evidence now suggests that epinephrine (a catecholamine) increases the formation of platelet clots in the blood, 🩸 which can block arteries and cause a heart attack. 🚫❤️
🏥 Medical Treatment and Rehabilitation of Cardiac Patients
Heart attack treatment follows a sequence from emergency care to a program of rehabilitation. 📋
🚑 Initial Treatment for Heart Attack
When heart attack victims enter the hospital, they receive emergency medical treatment to prevent or limit damage to the myocardium. 💊 Part of this treatment generally involves using clot-dissolving medication to free blocked arteries. Most patients are then placed in coronary care units, 🏥 where medical staff can monitor their physiological functioning closely. The risk of another attack is high during the first few days. ⚠️
As you might expect, most cardiac patients experience extremely high levels of anxiety in the first day or two of coronary care. 😰 The cardiac patients with the greatest difficulty coping are not necessarily the ones who are the most seriously ill—instead, they tend to be those who were experiencing distress and social problems before the heart attack. Excessive anxiety, depression, or denial can impair recovery, 🚫 and psychological intervention may be needed. For example, some patients may deny they had a heart attack and insist on leaving the hospital too early. ⏰ Many patients anticipate psychosocial problems ahead, particularly in relation to their work. 💼 A program for rehabilitation generally begins after the first week, when cardiac patients are transferred to a general ward. 🏥
💪 Rehabilitation of Cardiac Patients
Rehabilitation programs for heart attack patients are designed to promote recovery and reduce risk factors for having another attack. 🎯 These programs provide patients with information on such topics as lifestyle changes and restrictions they should follow, medications to take and symptoms to expect. 📋
To reduce the likelihood of another infarction, most cardiac patients receive advice on lifestyle changes, such as to: ✅
- 🚭 Quit smoking
- ⚖️ Lose weight
- 🏃♂️ Exercise
- 🥗 Reduce dietary fat and cholesterol
- 🍺❌ Reduce high alcohol consumption
Because stress and hostility are linked to heart disease, 😤 these patients often receive training in stress management, too. 🧘 Many heart attack victims who make healthful changes in their lifestyles and attitudes live longer than comparable people who have not had infarctions. ⏳✨
Some cardiac patients find it easy to adhere to their rehabilitation programs; ✅ others do not, and may resent the restrictions their conditions impose. 😠 One man said of his doctor's advice: "If he tells you that you cannot walk upstairs, he is telling you that you are weak, that you are no longer strong. He has taken something away from you; your pride." 💔 In addition, coronary patients with low self-efficacy for carrying out their medical regimens and who perceive little social support in their lives show less adherence to their regimens and slower recovery than those who have high levels of social support. 🤝💕
😔 The Psychosocial Impact of Heart Disease
"Is it OK for me to drive a car, do chores around the house, or lift heavy things?" 🚗🏡 heart attack patients often ask their doctors, fearing that overexertion could bring on new attacks. The extent of patients' disability is likely to affect how well they and their family adjust to their conditions. 👨👩👧👦
💼 Returning to Work
Being able to work has a special meaning to individuals who suffer from chronic health problems. 💪 People who have suffered heart attacks, for instance, often view returning to work as an important sign that they are recovering. ✅ Advice about returning to work depends on how severe the heart condition is and the physical requirements of the job. In the past, most individuals were advised to wait about 60 days before returning to work if the condition was not very severe. ⏳ But jobs in industrialized countries have become less physically demanding. 💻 Research has found that most cardiac patients can resume working about 2 weeks earlier without increasing their risk of another cardiac episode. 🎯
Physicians often advise people with heart disease to cut back on the amount of physical effort and stress they experience on the job. 📉 Following this advice may mean finding a new job, which may be difficult to do, particularly for people over age 50 or so. 👴 Patients who are near retirement age may simply leave the work force if they can. Nevertheless, most cardiac patients do go back to work, often with jobs that require less productivity or shorter hours than they previously had worked. ⏰ Studies have found that roughly 30% of cardiac victims who were previously employed return to some type and amount of work within the year following the heart attack. 📊
Sometimes cardiac patients' work restrictions cause them to experience interpersonal problems with coworkers and heightened work stress. 😰 Going back to work usually contributes to the long-term well-being of a cardiac victim. 💚 But the work situation can also create problems that may impair the person's physical and psychosocial condition. ⚠️
👨👩👧👦 Family Relationships
Cardiac illness and family relationships are closely interrelated. 💕 Studies have found that cardiac patients with strong social support recover faster and survive longer than those with less support. 🤝✨
For many heart patients, family difficulties—such as quarreling over financial 💸 or sexual problems 💑—existed prior to the infarction, and these difficulties often become worse. The illness adds to the original difficulties, such as by making the financial and sexual problems worse. What also seems to happen in these families is that a cycle of guilt and blame tends to develop. 😔
For example, a husband who suffers a myocardial infarction may blame his wife or children for his condition, 👉😠 and they may agree and feel guilty. 😢 But even when harmonious relations exist before the attack, the illness adds to the stress of all members of the family. 😰 Families have an enormous impact on the process of cardiac rehabilitation: patients adjust better, adhere more closely to their regimens, and recover sooner if their efforts receive family encouragement. 💪💕
