What Is Angina?

  it is chest pain that happens because there isn't enough blood going to part of your heart. It can feel like a heart attack, with pressure or squeezing in your chest. It’s sometimes called angina pectoris or ischemic chest pain.  

What are Antianginal agents?

  The name antianginal agents is employed for the group of drugs that are employed in angina management.  Angina is a health condition in which there is a narrowing of the coronary arteries (the arteries of the heart). The ache in chest is the main symptom of it.  

Examples of antianginal agents include

  Nitrates (eg, isosorbide dinitrate, isosorbide mononitrate, and nitroglycerin). They act in a way that makes the smooth muscles within the blood vessels to widen and this makes it easy for oxygen and blood to reach the heart. Calcium channel blockers (eg, diltiazem, nifedipine, nimodipine, verapamil). These are the agents which do not give calcium into the cells so as to inhibit the contraction of the vascular smooth muscle. Atenolol, pindolol, propranolol, metoprolol - beta-receptors blockers. These are on the heart, which will make it not to work hard as it would when it is not taking in the smoke. Ranolazine. Whether it is channel inhibition during cardiac repolarization or some other mechanism is unknown, but it is believed that it acts on the cardiac repolarization process in some way.  

Symptom

  It's a symptom of heart disease, and it happens when something blocks your arteries or there's not enough blood flow in the arteries that bring oxygen-rich blood to your heart. itusually goes away quickly. Still, it can be a sign of a life-threatening heart problem. It's important to find out what's going on and what you can do to avoid a heart attack. Usually, medicine and lifestyle changes can control angina. If it's more severe, you may need surgery, too. Or you may need what’s called a stent, a tiny tube that props open arteries.  

There are different types of angina:

  Stable angina. This is the most common. Physical activity or stress can trigger it. It usually lasts a few minutes, and it goes away when you rest. It isn't a heart attack, but it can be a sign that you're more likely to have one. Tell your doctor if this happens to you. You can have this while you're at rest or not very active. The pain can be strong and long-lasting, and it may come back again and again. It can be a signal that you're about to have a heart attack, so see a doctor right away.  

Microvascular angina

  With this type, you have chest pain but no coronary artery blockage. Instead, it happens because your smallest coronary arteries aren’t working the way they should, so your heart doesn’t get the blood it needs. The chest pain usually lasts more than 10 minutes. This type is more common in women.  

Prinzmetal's angina

  This type is rare. It might happen at night while you're sleeping or resting. Your heart arteries suddenly tight or narrow. It can cause a lot of pain, and you should get it treat.  

What Causes Angina?

  Angina pectoris, the lack of oxygen in the heart muscles, is a disease that can be caused by insufficient blood flow.  It may suggest CAD, a condition of the coronary arteries. This occurs when the arteries supplying blood to the heart lining become narrowed and almost occluded.  This may occur due to various conditions, including: • Arterial stiffening or the term atherosclerosis are things that are also associated with this. • A blood clot • The blood flow gets restricted due to the valves that are too small to let the blood through. • coronary artery spasm • Plaque is a risk of a rupture of an artery. • The heart muscle pumping reduced.
