Show Instruct patient to notify nurse immediately when chest pain occurs. Pain and decreased cardiac output may stimulate the sympathetic nervous system to release excessive amounts of norepinephrine, which increases platelet aggregation and release of thromboxane A2. This potent vasoconstrictor causes coronary artery spasm, which can precipitate, complicate, and/or prolong an anginal attack. Unbearable pain may cause vasovagal response, decreasing BP and heart rate. Assess and document patient response to medication. Provides information about disease progression. Aids in evaluating effectiveness of interventions, and may indicate need for change in therapeutic regimen. Identify precipitating event, if any: frequency, duration, intensity, and location of pain. Helps differentiate this chest pain, and aids in evaluating possible progression to unstable angina. Observe for associated symptoms: dyspnea, nausea and vomiting, dizziness, palpitations, desire to micturate. Decreased cardiac output (which may occur during ischemic myocardial episode) stimulates sympathetic and parasympathetic nervous system, causing a variety of vague sensations that patient may not identify as related to anginal episode. Evaluate reports of pain in jaw, neck, shoulder, arm, or hand (typically on left side). Cardiac pain may radiate. Pain is often referred to more superficial sites served by the same spinal cord nerve level. Place patient at complete rest during anginal episodes. Reduces myocardial oxygen demand to minimize risk of tissue injury. Elevate head of bed if patient is short of breath. Facilitates gas exchange to decrease hypoxia and resultant shortness of breath. Monitor heart rate and rhythm. Patients with unstable angina have an increased risk of acute life-threatening dysrhythmias, which occur in response to ischemic changes and/or stress. Monitor vital signs every 5 min during initial anginal attack. Blood pressure may initially rise because of sympathetic stimulation, then fall if cardiac output is compromised. Tachycardia also develops in response to sympathetic stimulation and may be sustained as a compensatory response if cardiac output falls. Stay with patient who is experiencing pain or appears anxious. Anxiety releases catecholamines, which increase myocardial workload and can escalate and/or prolong ischemic pain. Presence of nurse can reduce feelings of fear and helplessness. Maintain quiet, comfortable environment. Restrict visitors as necessary. Mental/emotional stress increases myocardial workload. Provide light meals. Have patient rest for 1 hr after meals. Decreases myocardial workload associated with work of digestion, reducing risk of anginal attack. Provide supplemental oxygen as indicated. Increases oxygen available for myocardial uptake and reversal of ischemia. Administer antianginal medication(s) promptly as indicated:
What is coronary artery disease involving native coronary artery of native heart with angina pectoris?Coronary artery disease (CAD) is a condition that affects your coronary arteries, which supply blood to your heart. With CAD, plaque buildup narrows or blocks one or more of your coronary arteries. Chest discomfort (angina) is the most common symptom.
What does coronary artery disease in native artery mean?Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Plaque is made up of cholesterol deposits. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis.
Is angina pectoris the same as coronary artery disease?Angina is a symptom of coronary artery disease. Angina is also called angina pectoris. Angina pain is often described as squeezing, pressure, heaviness, tightness or pain in the chest. It may feel like a heavy weight lying on the chest.
Is angina pectoris serious?Angina is chest pain caused by reduced blood flow to the heart muscles. It's not usually life threatening, but it's a warning sign that you could be at risk of a heart attack or stroke. With treatment and healthy lifestyle changes, it's possible to control angina and reduce the risk of these more serious problems.
