Sublingual nitroglycerin — Sublingual (under the tongue) nitroglycerin (NTG) is usually recommended to treat sudden attacks of angina and to prevent angina while engaging in activities that typically trigger angina, such as mowing the lawn, playing sports, or walking up a hill (especially in the cold).
If you have stable angina (the most common type), you'll be given medicine to take when you have an angina attack. This is called glyceryl trinitrate, or GTN. It comes as a mouth spray or tablets that dissolve under your tongue.
Three major classes of anti‐ischaemia drugs are currently used in the medical management of angina pectoris: β‐blockers, nitrates (short‐ and long‐acting), and calcium channel antagonists (table 1).
Because angina can be related to the rate of blood flow to the heart, and because the symptoms are similar to those of a heart attack, taking an aspirin at the onset of symptoms is recommended. The aspirin prevents blood clots from forming and may reduce the size of a clot that has already formed.
As secondary prevention, aspirin is believed to be effective in acute coronary syndrome, stable angina, revascularization, stroke, TIA, and atrial fibrillation.
If your angina gets worse or changes, seek emergency medical help immediately.
If the blood flow doesn't improve, the heart is starved of oxygen and a heart attack occurs. Unstable angina is dangerous and requires emergency treatment. Variant angina (Prinzmetal angina). Variant angina, also called Prinzmetal angina, isn't due to coronary artery disease.
Call 911 if a person who has been diagnosed with and is being treated for angina begins to experience a crushing sensation; stabbing pain; numbness in the chest; or discomfort in the neck, jaw, arms or back.
You may have tests to check if you have angina and assess your risk of more serious problems like heart attacks or stroke. You may have: an electrocardiogram (ECG) – a test to check your heart's rhythm and electrical activity.
If the pain is relieved within a minute or two with nitroglycerin, a medicine used to treat angina, it suggests (but does not prove) that ischemia is the cause (see 'Nitroglycerin' below). Other conditions, especially muscular spasms or esophageal spasm, may also improve with nitroglycerin.
Nitroglycerin. If you typically use nitroglycerin to relieve angina and if one dose of nitroglycerin has not relieved your symptoms within 5 minutes, call 911. Do not wait to call for help. Symptoms can vary.
Unstable angina should be treated as an emergency. If you have new, worsening or persistent chest discomfort, call 911 and go to the emergency room. You could be having a heart attack, increasing risk for severe cardiac arrhythmias or cardiac arrest, which could lead to sudden death.
Angina is usually caused by the arteries supplying blood to the heart muscles becoming narrowed by a build-up of fatty substances. This is called atherosclerosis. Things that can increase your risk of atherosclerosis include: an unhealthy diet.
Nitroglycerin — usually taken as a tablet under the tongue — relaxes heart arteries, so blood can flow more easily through the narrowed spaces.
Angina chest pain is usually relieved within a few minutes by resting or by taking prescribed cardiac medicine, such as nitroglycerin. An episode of angina means some part of the heart is not getting enough blood supply.
Adults—1 tablet placed under the tongue or between the cheek and gum at the first sign of an angina attack. 1 tablet may be used every 5 minutes as needed, for up to 15 minutes. Do not take more than 3 tablets in 15 minutes. To prevent angina from exercise or stress, use 1 tablet 5 to 10 minutes before the activity.
They found that low vitamin D deficiency (VitD) was associated with angina.
Angina affects both men and women, but at different ages based on men and women's risk of developing coronary heart disease. In men, heart disease risk starts to increase at age 45. Before age 55, women have a lower risk for heart disease than men. After age 55, the risk rises in both women and men.
Coronary heart disease occurs when there's narrowing of the coronary arteries supplying blood to the heart muscles, due to a build-up of a fatty substance in the arteries (plaque). Angina is not the same as a heart attack. Unlike a heart attack, angina does not cause permanent damage to the heart muscle.
Usually lasts 5 minutes; rarely more than 15 minutes. Triggered by physical activity, emotional stress, heavy meals, extreme cold or hot weather. Relieved within 5 minutes by rest, nitroglycerin or both. Pain in the chest that may spread to the jaw, neck, arms, back or other areas.
When a coronary artery is at least 60 – 70 % blocked and stable, most commonly angina is brought on by physical activity or stress or emotional stress which leads to myocardial ischemia.
Symptoms of unstable angina include: Tight or crushing pain in your chest that may spread to other areas in your upper body. Chest pain that happens even when you're not exerting yourself.
The results show that during acute coronary syndrome (mostly STEMI) it is beneficial to give aspirin first and give nitroglycerin several minutes later.
Nitroglycerin is contraindicated in patients that have reported allergic symptoms to the medication. [18] Known history of increased intracranial pressure, severe anemia, right-sided myocardial infarction, or hypersensitivity to nitroglycerin are contraindications to nitroglycerin therapy.
