The heart beat
The heart is a muscular organ responsible for pumping oxygenated, nutrient-rich blood throughout the body.
The heart is the hardest working muscle in the body beating at an average of around 72 beats per minute.
There are two primary causes of heart disease: 1) clogged arteries and 2) direct damage to the heart muscle itself due to other factors.
Heart disease is the leading cause of death for people in the United States - almost 2,000 Americans die of heart disease each day.
Heart disease
Heart disease include heart and vascular problems in itself.
Heart needs the oxygen strictly for it works hard.
Meanwhile, the cardiac cells have been differentiated completely that it cannot be regenerated.
So, the myocardial cell will not be able to repair once being injured.
The cholesterol and other substances may cause smooth vascular endothelium cell injured and the cumulative platelets around damaged parts will make vascular congestion, poor efficiency in the oxygen supply, hypoxic myocardial cell necrosis.
This can be detected through blood test , a special enzyme presented in of myocardial cells, to prove whether a myocardial necrosis or not.
Take medicine
Your doctor may prescribe a variety of heart medications you can take to treat or prevent heart disease. These drugs may help lower your blood pressure, reduce the level of cholesterol in your blood, or help the body get rid of excess fluids that put a strain on the heart's ability to pump blood.
□Heart medication needs vary for each person. Whatever the treatment protocol prescribed to you, it is a good idea to keep the following guidelines in mind when you're taking heart disease drugs.
□Know the names of your heart medications and how they work.
□Know the generic and brand names, dosages, and side effects of the drugs.
□Always keep a list of your medications with you.
□Take heart medications as scheduled, at the same time every day.
□Do not stop taking or change medications unless you first talk with your doctor.
□Even if you feel good, continue to take your medications. Stopping these drugs suddenly can make the condition worse.
□Have a routine for taking heart medications.
□Get a pillbox that is marked with the days of the week.
□Fill the pillbox at the beginning of each week to make it easier to remember.
□Keep a medicine calendar and note every time you take a dose.
□The prescription label tells how much to take at each dose, but your doctor may change the dosage periodically, depending on your response to the drug.
□On your medication calendar, you can list any changes in dosages as prescribed by your doctor.
□Do not decrease a drug's dosage to save money.
□You must take the full amount to get the full benefits.
□Do not take any over-the-counter drugs or herbal therapies unless you ask your doctor first.
□Some drugs, such as antihistamines (including Benadryl and Dimetapp), and nonsteroidal anti-inflammatory agents (NSAIDs, such as Advil, Motrin, and Indocin), can worsen heart failure symptoms.
□If you forget to take a dose, take it as soon as you remember. However, if it is almost time for the next dose, ask your doctor about skipping versus making up the missed dose.
□Regularly fill prescriptions and ask your pharmacist any questions you have.
Arrhythmias
Has your heart ever skipped a beat? Sometimes it really does if you have an arrhythmia. An arrhythmia is any disorder of your heart rate or rhythm.
It means that your heart beats too quickly, too slowly or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia. When the heart beats too slowly, it is called bradycardia.
Many factors can affect your heart's rhythm, such as having had a heart attack, blood chemistry imbalances or abnormal hormone levels. Some substances or medicines may also cause arrhythmias.
Symptoms of arrhythmias include：
□Fast or slow heart beat
□Skipping beats
□dizziness
□Chest pain
□Shortness of breath
□Paleness
□Sweating
Good for heart
Blood pressure control:
□No risk factor: 140 / 90mmHg
□Angina pectoris
or coronary heart disease: 130 / 80mmHg
□Diabetes: 130 / 80mmHg
□Renal lesions
□proteinuria: 125 / 75mmHg
□end-stage renal disease
or kidney dialysis: 130 / 80mmHg
Nutrition for heart
□Recently published in JAMA (Journal of the American Medical Association) an article stated that women with high fiber diets will greatly reduce the risk of coronary heart disease (coronary heart disease, CHD).
□The study found that take 22.9 grams of fiber a day, the risk of coronary heart disease is 53% lower than average only take 11.5 grams a day.
□Each increased 5 grams of daily fiber intake, the risk of coronary heart disease will declined 37% .
□Coronary heart disease is strongly related with the exists too much LDL and triglyceride (sign for getting older and lacking exercise) in blood. As LDL being oxidized in vascular, will cause series reaction of mass formed.
□If unfortunately this mass blocking in coronary (the artery supplies oxygen to the heart), will caused heart hypoxia necrosis.
□Past studies have shown that intake fiber can reduce LDL cholesterol concentration, thus greatly reduced oxidation of LDL, and intake natural foods which are rich with antioxidant also can prevent LDL oxidation and then, prevention of cardiovascular disease.
Exercise for heart
□The benefits of exercise forthe blood vessels and the heart is to increase the efficiency of blood circulation, most important is that exercise can improve vascular endothelial function of dilated blood vessels, decrease blood vessel inflammation, promote the metabolism of skeletal muscles ,increase blood oxygen concentrations and utilization, reduce the occurrence of ischemia.
□For full efficiency of exercise, you need to exercise three times a week, more than 30 minutes every time, and get the exercise intensity (up to feel a little pain).
Cardiovascular health management
□Cardiovascular health management can be divided into primary and secondary prevention of cardiovascular disease prevention program.
□Primary prevention is for generally healthy people to get the effects of cardiovascular disease prevention.
The major is to earn daily health habits to reduce the health risk factors. You can start from healthy diet, exercise, and preventive screening as health self-management to prevent the risk of cardiovascular disease.
□Secondary prevention is to provide rehabilitation plans to improve rehabilitation of cardiovascular disease and reduce the risk of relapse. So that patients can return to their daily lives as soon as possible.
□Secondary prevention is "cardiac rehabilitation", increasing the effects of cardiac rehabilitation and reduce risk when engaging in activities.
□ "Cardiac rehabilitation" is for heart disease patients with a range of medical and health-care services, including medical assessments, exercise prescription, risk factor correction, counseled, and health education.
□Rehabilitation of the heart's main purpose is to enable the patient to increase capacity of functional activities, reduce the symptoms, decrease risk factors, and enhance the quality of life.
Quit smoking
□Nicotine in cigarettes would stimulate the sympathetic, accelerated heart beats, causing peripheral vascular and coronary vasoconstriction, leading to myocardial hypoxia, increased blood pressure, hypertension.
□In addition, smoking can increase free radicals in the body, cholesterol oxidized, oxidation of cholesterol that can accumulate in the arteries and harden it, all these increase opportunities for vascular thrombosis .
