Insights

Post-procedural chest pain (PPCP) is common after percutaneous coronary intervention (PCI) in stable angina patients. Abnormal ECG changes, troponin I elevation, and stent number predict PPCP.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Clinical Medicine

Background:

  • Percutaneous coronary intervention (PCI) is widely used for acute coronary syndrome.
  • PCI is an additional treatment for refractory angina.
  • Post-PCI chest pain (PPCP) is a common issue, but its causes in stable angina are unclear.

Purpose of the Study:

  • To determine the incidence and predictors of post-PCI chest pain (PPCP) in patients with stable angina.
  • To understand the clinical implications of PPCP in this patient group.

Main Methods:

  • Retrospective collection of clinical data from 167 stable angina patients undergoing elective PCI.
  • Comparison of 70 patients with PPCP to 97 patients without PPCP within 24 hours post-procedure.
  • Analysis of incidence and predictors of PPCP.

Main Results:

  • The incidence of PPCP was 41.9%.
  • PPCP patients showed more abnormal post-PCI ECG changes, elevated cardiac troponin I (cTnI), more PCI vessels, and stent placements.
  • PPCP was strongly correlated with abnormal post-PCI ECG, cTnI elevation, and number of stents placed.

Conclusions:

  • Post-PCI chest pain (PPCP) is a frequent occurrence in stable angina patients.
  • Abnormal ECG changes, cTnI elevation, and the number of stents placed are significant predictors of PPCP.
  • PPCP patients required more repeat revascularization.

Angina III: Clinical Manifestations and Assessment

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 V: Nursing Management

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 II: Classification

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...

Angina I: Introduction

Definition and Symptoms: Angina (angina pectoris) is chest pain or discomfort caused by myocardial ischemia, which occurs when the heart muscle receives insufficient oxygen-rich blood. It typically manifests as pressing, squeezing, or crushing sensations in the chest and may radiate to the shoulders, arms, neck, jaw, or back.Primary Cause: In a healthy state, the coronary arteries can dilate (widen) to increase blood flow and meet the increased oxygen demand during physical activity or...

Angina IV: Management

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...

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...
