Summary
Acupressure on highly sensitive acupoints significantly reduced angina episodes compared to low-sensitivity points. This therapy offers a promising approach for managing stable angina pectoris.
Area of Science:
- Integrative Medicine
- Cardiology
- Pain Management
Background:
- Acupoint sensitization is a key factor in acupoint therapy's effectiveness.
- Evaluating acupressure for stable angina prevention based on acupoint sensitivity is crucial.
Purpose of the Study:
- To assess the efficacy of acupressure in preventing stable angina pectoris.
- To compare outcomes using acupoints with high versus low pressure-pain sensitivity.
Main Methods:
- 202 patients were randomized into high-sensitivity (HSG) or low-sensitivity (LSG) acupressure groups.
- Treatment lasted 4 weeks, with evaluations at baseline, week 4, and week 8.
- Primary outcome: change in angina attack frequency; secondary outcomes: nitroglycerin use, CCS class, SAQ score.
Main Results:
- HSG showed significantly better angina frequency reduction than LSG at weeks 4 and 8 (IRR 0.691-0.692).
- No significant difference in nitroglycerin consumption between groups.
- HSG reported greater improvements in angina frequency and treatment satisfaction scores.
Conclusions:
- Acupressure applied to high-sensitivity acupoints effectively reduces stable angina pectoris episodes.
- This method presents a potentially effective non-pharmacological intervention for angina management.
- The study is registered under NCT03975140.

IntroductionThe management of angina requires a comprehensive approach that includes pharmacological therapies, medical procedures, and lifestyle modifications.Pharmacological TherapiesAntiplatelet agents, such as aspirin, clopidogrel, prasugrel, and ticagrelor, play a pivotal role in preventing thrombus formation in patients with angina. These medications inhibit platelet aggregation and reduce the likelihood of myocardial infarction and other cardiovascular events.Anticoagulants, including...

Angina, a symptom of myocardial ischemia, requires a structured nursing management approach to ensure effective care and prevent complications like myocardial infarction. Comprehensive nursing care involves assessing, diagnosing, planning, implementing interventions, and evaluating outcomes, all tailored to the individual patient's needs.Patient AssessmentNursing assessment begins with a detailed subjective evaluation of symptoms, which typically include chest pain or pressure radiating to the...

Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...

Angina, also known as angina pectoris, is a chest pain resulting from diminished blood flow to the heart muscle and is often a symptom of coronary artery disease. Angina presents several variants with distinctive attributes, etiologies, and therapeutic approaches. The main types of angina include stable, unstable, variant (Prinzmetal's), microvascular, intractable, and silent ischemia.Stable angina is caused by atherosclerosis, which leads to the formation of plaques that narrow the coronary...

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...
