How to treat angina?
The best treatment for your angina depends on the type of angina you have and other factors. If your angina is stable, you might be able to control it with lifestyle changes and medicines. Unstable angina requires immediate treatment in a hospital, which could involve medicines and surgical procedures.
What is the most common type of angina?
Types of angina. Angina is pain, discomfort or pressure in the chest. The most common types are chronic stable angina and unstable angina. Chronic stable angina. Chest pain occurs when your heart is working hard enough to need more oxygen, such as during exercise. The pain can go away when you rest.
How to treat angina with nitrates?
Several medications can improve angina symptoms, including: 1 Aspirin. Aspirin and other anti-platelet medications reduce the ability of your blood to clot, making it easier for blood to flow through narrowed heart arteries. 2 Nitrates. Often used to treat angina, nitrates relax and widen your blood vessels, allowing more blood to flow to your heart muscle. Nitrates in pills or sprays act quickly to relieve pain during an event. There are also long-acting nitrate pills and skin patches. 3 Beta blockers. These block the effects of the hormone epinephrine, also known as adrenaline. They help your heart beat more slowly and with less force, decreasing the effort your heart makes and easing the angina pain. 4 Statins. Statins lower blood cholesterol by blocking a substance your body needs to make cholesterol. They might also help your body reabsorb cholesterol that has accumulated in the buildup of fats (plaques) in your artery walls, helping prevent further blockage in your blood vessels. 5 Calcium channel blockers. Also called calcium antagonists, these drugs relax and widen blood vessels by affecting the muscle cells in the arterial walls. This increases blood flow in your heart, reducing or preventing angina. 6 Ranolazine (Ranexa). This anti-angina medication might be prescribed with other angina medications, such as beta blockers. It can also be used as a substitute if your symptoms don't improve with the other medications.
What to do if your angina is not working?

Air pressure causes the cuffs to inflate and deflate in time to your heartbeat. This typically requires getting five one-hour treatments a week for seven weeks .
What are the key interventions for angina?
Key interventions include lifestyle changes (eg smoking cessation, dietary modification and increased physical exercise), management of hypertension, diabetes and obesity, and other secondary cardiovascular disease prevention measures, such as the use of anti-platelet and lipid-lowering agents, pharmacological anti-anginal therapies and percutaneous and/or surgical revascularisation when appropriate.4,5
What is angina pectoris?
The term angina pectoris refers to William Heberden's classic description of the clinical symptoms of angina , as reported to the Royal College of Physicians in 1768.1There is currently no systematically agreed definition for angina pectoris and the term is used to define both the typical chest pain associated with myocardial ischaemia and the syndrome characterised by chest pain, myocardial ischaemia and obstructive atherosclerotic coronary artery disease. In this article, we use the term ‘angina’ in relation to the occurrence of typical central chest pain associated with myocardial ischaemia, irrespective of the presence or absence of flow-limiting organic coronary artery stenosis.
What is the ACOVA test?
In the ACOVA (Abnormal Coronary VAsomotion in patients with stable angina and unobstructed coronary arteries) study, approximately two-thirds of patients without significant epicardial CAD had positive intra-coronary acetylcholine tests for distal epicardial or microvascular spasm.13Clinicians should be encouraged to think about the possibility of microvascular dysfunction or coronary microvascular spasm in patients who present with typical angina despite having angiographically normal coronary arteries.
What causes angina in the heart?
This often occurs as a direct result of flow-limiting CAD, but it can also be due to coronary artery spasm limiting blood supply, coronary microvascular dysfunction and/or several other contributing mechanisms . To a great extent, the underlying pathogenic mechanism determines the pattern of clinical presentation, leading to effort-induced angina, mixed angina or angina at rest.
How long does angina last?
Angina is considered to be ‘chronic’ and ‘stable’ when symptoms are present for at least two months, without changes in severity, character or triggering circumstances.2
What is CAD in angina?
The Canadian Cardiovascular Society (CCS) grading of angina is a functional classification of exercise tolerance that can be related to metabolic equivalent units (METs) and it is used in the assessment of exercise stress testing.7,8
Does Nicorandil help with vasodilatation?
Nicorandil acts as both a nitric oxide donor and a sarcolemmal K+-adenosine triphosphate (K-ATP)-dependant channel opener, causing K+efflux and subsequent hyperpolarisation and inhibition of L-type Ca2+channels, leading to systemic and coronary vasodilatation. The beneficial effects of nicorandil monotherapy are similar to those of metoprolol, amlodipine, diltiazem and nitrates.20–23In the IONA (Impact Of Nicorandil in Angina) study, a reduced rate of fatal and non-fatal myocardial infarction and reduced admission for cardiac chest pain were seen in patients taking nicorandil in addition to other standard anti-anginal therapies.24The cardio-protective properties of nicorandil might be due to ischaemic preconditioning mediated by activation of mitochondrial K-ATP channels.24Common side effects of nicorandil are headaches, dizziness, nausea, vomiting and flushing. Metformin might antagonise the effects of nicorandil by closing K-ATP channels.25The use of phosphodiesterase-5 inhibitors and nitrates should be avoided by those taking nicorandil because of the risk of profound systemic hypotension.
How many drops of beta blocker per minute?
4. 38 drops/minute. When treating angina, the nurse knows that the mechanism of action of a beta-adrenergic blocker is: 1. Slowed heart rate and decreased contractility of the heart. 2. Relaxation of arterial and venous smooth muscle. 3. Increased contractility and heart rate.
What is LPN/LVN?
The license d practical/vocational nurse (LPN/LVN) is assisting the registered nurse in the development of a patient care plan. She recognizes that the patient is going to be receiving what class of medication that decreases heart rate, contractility, and blood pressurem and is used to increase survival rates in post-MI patients?
What are the medications used for angina pectoris?
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 11). All three have been shown to prolong the duration of exercise before the onset of angina and ST segment depression as well as to decrease the frequency of angina. However, none prevents MI or death caused by coronary disease in patients being treated specifically for chronic stable angina.
What are the lifestyle changes that can help with angina?
Therefore, risk factor modification should be the central component of management.11Suggested lifestyle changes include cessation of smoking, exercise and weight reduction, in addition to treatment of hypertension and glycaemic control in patients with diabetes. There are also numerous drugs available to improve prognosis by preventing MI and death.
What is the mode of action of antianginal drugs?
The mode of action of most conventional antianginal agents involves haemodynamic changes, such as a reduction in systemic vascular resistance or coronary vasodilatation or negative inotropism, which improve the imbalance in myocardial oxygen supply and demand. Recently, new drugs based on novel mechanisms of action have emerged6(table 11).
Does CABG improve survival?
Revascularisation with CABG was found to improve survival compared to medical management in selected patients with stable angina: patients with left main or three‐vessel coronary disease ; patients with two‐vessel disease and significant lesions in the proximal left anterior descending artery; and patients with multivessel disease in the presence of left ventricular dysfunction or diabetes.
Is trimetazidine safe for angina?
In a Cochrane meta‐analysis of 23 studies including 1378 patients, trimetazidine was associated with a significant reduction in weekly angina episodes and improved exercise time to 1 mm ST segment depression compared to placebo.8In patients with stable angina who experienced concomitant erectile dysfunction, trimetazidine plus sildenafil was both safe and more effective in controlling episodes of ischaemia during sexual activity than nitrates alone. These data indicate that trimetazidine is safe and effective for the treatment of symptoms of stable angina, either as monotherapy or adjunctive treatment.
Is stable angina pectoris a disease?
Coronary artery disease is still highly prevalent worldwide, and stable angina pectoris is one of its more common presentations. Stable angina is a clinical expression of myocardial ischaemia associated with fixed atherosclerotic coronary stenosis, which prevents the adaptation of coronary perfusion to an increased oxygen requirement. The goals of treatment include relief of symptoms, inhibition or slowing of disease progression, prevention of future cardiac events such as myocardial infarction (MI), and improved survival. This article reviews the treatment modalities currently available to alleviate the symptoms of chronic angina and to reduce the risk of future MI and cardiac death, including several novel pharmacological treatments, coronary revascularisation, as well as novel technologies that may benefit selected groups of patients who are refractory to both drugs and revascularisation (fig 11).
Does Nicorandil help with vasodilation?
Nicorandil exerts dual actions: it increases the opening of ATP‐gated K+channels, thereby relaxing smooth muscle and contributing to coronary vasodilatation; and it has a nitrate‐donating moiety. Nicorandil may mimic the natural process of ischaemic preconditioning, which involves ATP‐dependent potassium channels. Several small randomised trials of patients with stable angina have shown that nicorandil prolongs the time to onset of ST depression and exercise duration during stress testing and improves myocardial perfusion at rest and with exercise. In the IONA trial of 5126 patients, the administration of nicorandil in addition to standard treatments reduced the primary end point (coronary death, MI, or hospitalisation for angina) by 17% after a mean follow‐up of 1.6 years. There was also a significant reduction in the incidence of acute coronary syndrome and all cardiovascular events.9
