Insights

The Korean version of the Coronary Revascularization Outcome Questionnaire (CROQ-K) is a reliable tool for assessing health-related quality of life in patients after percutaneous coronary intervention (PCI). This study confirms its validity and reliability for this patient group.

Area of Science:

  • Cardiology
  • Health Outcomes Research
  • Psychometrics

Background:

  • Ischemic heart disease prevalence is rising, increasing the importance of health-related quality of life (HRQOL).
  • The Coronary Revascularization Outcome Questionnaire (CROQ) is a key instrument for evaluating HRQOL in coronary artery disease patients.
  • Percutaneous coronary intervention (PCI) is a common treatment for coronary artery disease.

Purpose of the Study:

  • To validate the psychometric properties of the Korean version of the CROQ (CROQ-K).
  • To assess the reliability and validity of the CROQ-K in patients undergoing percutaneous coronary intervention (PCI).

Main Methods:

  • The CROQ was translated into Korean (CROQ-K).
  • 209 pre-PCI and 169 post-PCI patients completed the CROQ-K, SF-12, and SAQ-K.
  • Internal consistency, concurrent validity (vs. SF-12, SAQ-K), and construct validity (EFA) were assessed.

Main Results:

  • CROQ-K demonstrated good internal consistency (coefficients > 0.70, excluding adverse effects).
  • Concurrent validity was supported by correlations with SF-12 and SAQ-K.
  • Exploratory factor analysis identified 7 core factors, with large effect sizes for symptoms and psychosocial functioning.

Conclusions:

  • The Korean version of the CROQ (CROQ-K) is a valid and reliable measure.
  • CROQ-K is suitable for assessing HRQOL in Korean patients with coronary artery disease post-PCI.

Reliability and Validity01:29

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

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

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...
