Insights

Patients with lung cancer and ischemic heart disease undergoing surgery had low cardiac event rates after coronary interventions. Coronary stenting showed no major adverse events, including stent thrombosis.

Area of Science:

  • Cardiology
  • Thoracic Surgery
  • Oncology

Context:

  • Concomitant ischemic heart disease (IHD) is a concern in lung cancer patients undergoing surgery.
  • Prevalence of IHD in lung cancer surgical patients is approximately 4.7% in this cohort.
  • Management strategies for IHD in this population require careful consideration.

Purpose:

  • To evaluate the outcomes of cardiac interventions in lung cancer patients with concomitant IHD.
  • To assess the safety and efficacy of coronary artery procedures, including stenting, in this high-risk group.
  • To analyze the impact of perioperative medications on surgical outcomes.

Summary:

  • A review of 1,047 lung cancer patients revealed 49 with IHD.
  • 41 patients underwent coronary angiography, with 26 receiving coronary stents (bare metal or drug-eluting) and 3 undergoing balloon angioplasty.
  • Five patients had coronary artery bypass grafting, and eight had coronary spastic angina. Postoperative major adverse cardiac events were 6.1% with a 2.0% fatality rate. No cardiac events occurred in stented patients. Perioperative aspirin and heparinization did not significantly increase bleeding risk.

Impact:

  • Coronary interventions, particularly stenting, appear safe and effective in lung cancer patients with IHD.
  • This study supports the feasibility of managing concomitant IHD in lung cancer surgical candidates.
  • Findings suggest that perioperative anticoagulation and antiplatelet therapies can be safely administered without significantly increasing intraoperative bleeding.

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Acute Coronary Syndrome V: Nursing Management

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,...

Acute Coronary Syndrome IV: Interprofessional Care

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...

Pulmonary Embolism III: Nursing Management

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

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...
