Area of Science:

  • Cardiovascular Medicine
  • Health Services Research
  • Epidemiology

Background:

  • Comprehensive cardiovascular disease (CVD) monitoring is crucial in aging populations.
  • The Japanese Circulation Society (JCS) established the Japanese Registry Of All cardiac and vascular Diseases-Diagnosis Procedure Combination (JROAD-DPC) registry.
  • This registry links JROAD questionnaires with nationwide DPC administrative claims for patient-level CVD care analysis.

Purpose of the Study:

  • To provide a comprehensive overview of the JROAD-DPC registry.
  • To analyze temporal trends in CVD patient demographics, diagnoses, and interventions in Japan.
  • To support national CVD policy evaluation and improvement.

Main Methods:

  • Utilized anonymized data from April 2012 to March 2023.
  • Described temporal trends in patient demographics, CVD diagnoses, interventions, disease severity, and hospital characteristics.
  • Analyzed data from participating facilities and registered patients over time.

Main Results:

  • Participating facilities and registered patients significantly increased.
  • Median patient age increased, with a notable rise in individuals aged ≥90 years.
  • Trends showed declining angina pectoris admissions but increasing atrial fibrillation/flutter and heart failure admissions. Catheter ablations and percutaneous coronary interventions saw substantial increases.

Conclusions:

  • The JROAD-DPC registry captures over 1.5 million annual CVD hospitalizations, offering a large-scale, nationwide longitudinal view of cardiovascular care in Japan.
  • Its scale and validated coding facilitate robust analyses of trends and outcomes.
  • The registry is a valuable tool for national CVD policy evaluation and improvement.

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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

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...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Coronary Artery Disease V: Interprofessional Care

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...
