Insights

Routine cardiovascular investigations like transthoracic echocardiography (TTE) and Holter monitors are costly and low-yield in stroke patients. These tests rarely change treatment, suggesting a need for cost-effective criteria in stroke management.

Area of Science:

  • Cardiology
  • Neurology
  • Health Economics

Background:

  • Limited prospective randomized studies exist on routine cardiovascular investigations in stroke patients.
  • Ambulatory stroke clinics face challenges in optimizing diagnostic strategies.

Purpose of the Study:

  • To evaluate the utilization, clinical relevance, and economic impact of cardiovascular investigations in an ambulatory stroke clinic.
  • To assess the yield of transthoracic echocardiography (TTE) and Holter monitoring in stroke patients.

Main Methods:

  • Retrospective analysis of 200 stroke/transient ischemic attack patients.
  • Assessed TTE for thrombus, cardiac dysfunction, and structural abnormalities.
  • Defined relevance by treatment paradigm shift; ECG/Holter relevant for atrial fibrillation/flutter.

Main Results:

  • TTE and Holter monitoring were used in over 70% of cases, constituting 94% of cardiovascular costs.
  • Clinically relevant TTE findings occurred in only 4% of patients and did not alter antithrombotic therapy.
  • ECG and Holter identified only 2 new cases of atrial fibrillation.

Conclusions:

  • Transthoracic echocardiography and Holter monitoring appear to be low-yield, high-cost procedures in this stroke clinic setting.
  • Prospective studies are needed to establish cost-effective criteria for selecting cardiovascular investigations in stroke management.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Assessment of the Cardiovascular System I: Subjective Data

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...

Dysrhythmias V: Evaluating Dysrhythmias

Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
