What to expect before, during and after an MRI scan
If you’ve never experienced a magnetic resonance imaging (MRI) scan before, you might be anxious about what to expect.
Angina (also called angina pectoris) is chest pain associated with decreased blood flow to the heart. Although the “classic” pain is described as chest discomfort that radiates down the arm or up the jaw, it can occur in many different ways. For example, women have a different type of pain than men; in addition, people who have diabetes, particularly those who take insulin or have poorly controlled blood sugars and nerve damage elsewhere in the body (such as in the feet) may have minimal symptoms. Angina can be confused with gallbladder disease, stomach ulcers and acid reflux. It usually goes away within a few minutes with rest or with the use of nitroglycerin.
Angina is not the same as a heart attack although the symptoms may be similar. Chest pain that causes a heart attack does not typically stop. The chest pain from angina often occurs with physical activity. Other things that can trigger it are stress, smoking, extreme heat and cold, heavy meals and excessive alcohol consumption. Usually with angina, if you stop and rest for a few minutes or take a prescribed cardiac medication such as nitroglycerin, the pain stops.
Angina can be a symptom of coronary artery disease. This condition can be caused by high LDL (low-density lipoprotein) cholesterol, high triglyceride levels and reduced HDL (high-density lipoprotein) cholesterol; high blood pressure; physical inactivity; smoking; obesity; a diet high in saturated fat; and diabetes. These are risk factors that you can control. Risk factors you cannot control include family history, age and sex. Males are believed to be at higher risk of coronary artery disease than females, but this may be misleading. Women often have different symptoms and, therefore wait to seek medical care until they have much more advanced forms of disease. As with men, women's most common heart attack symptom is chest pain or discomfort. But women are somewhat more likely than men to experience some of the other common symptoms, particularly shortness of breath, nausea/vomiting and back or jaw pain.
Symptoms of angina vary but typically include:
Angina can be a symptom of coronary artery disease, also called coronary heart disease. In coronary artery disease, arteries that carry blood to the heart are narrowed or blocked, often due to atherosclerosis.
If you have angina, it does not necessarily mean you are going to have a heart attack. Angina does indicate that you have coronary artery disease and that your heart is not receiving an adequate blood supply. If you have angina, you have an increased risk of a heart attack.
Angina that occurs with exertion is called stable angina. Angina that changes in pattern from previously stable angina, is sudden or occurs at rest is called unstable angina and may indicate a heart attack is coming.
There are two other forms of angina:
Tests we use to diagnose the cause of angina and the extent of coronary artery disease include:
Medications prescribed for angina aim to increase blood flow to the heart muscle and decrease the workload of the heart. This increase of blood flow widens the blood vessels and relieves the pain you may experience with angina.
Nitroglycerin is the most commonly prescribed medication for people who have angina. Sometimes the arteries become tolerant of this medication and greater amounts may be required to have the same benefits.
Medications also may be prescribed to treat coronary artery disease, the underlying cause of angina. These medications include: Antiplatelet agents, anticoagulants, antihyperlipidemics (cholesterol-lowering drugs), beta-blockers and antihypertensives (blood pressure-lowering drugs).
If your symptoms are severe enough, your physician may recommend a nonsurgical minimally invasive procedure to treat the cause of angina, which is coronary artery disease. These cardiac catheterization procedures increase blood flow to the heart muscle and decrease the risk of a heart attack. If a blockage is found, then an angioplasty (also called percutaneous coronary intervention or PCI) can be performed. This procedure can include removing a clot by suctioning it out, opening the blocked artery with balloon angioplasty or placing a stent to restore blood flow to the heart muscle. These are common treatments. Ohio State’s Ross Heart Hospital performs more than 5,000 procedures a year, making it one of the highest volume centers in the area. Because we’ve done so many procedures, our staff is better equipped and more experienced in handling even the most difficult cases.
Coronary artery bypass graft (CABG) may be necessary to restore your coronary blood flow if you have had a heart attack.
Some patients have severe coronary artery disease and angina that cannot be treated with medication, stents or the CABG surgery mentioned above. In those cases, Ohio State heart surgeons can sometimes use a special laser to drill small holes in the heart to improve blood flow. In extreme cases, heart transplantation may be considered.
