Insights

Fractional flow reserve (FFR) use in elderly patients undergoing elective coronary angiography is low at 6.3%. Factors like age, sex, race, and region impact FFR adoption, indicating barriers to its widespread use.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Economics

Background:

  • Fractional flow reserve (FFR) assesses coronary artery perfusion.
  • FFR use is associated with improved outcomes and reduced costs in elective coronary angiography.
  • Nationwide surveys indicate low FFR adoption despite proven benefits.

Purpose of the Study:

  • To investigate the utilization of FFR in elderly patients undergoing elective coronary angiography.
  • To identify predictors of FFR use in this specific demographic.

Main Methods:

  • Retrospective analysis of patient data undergoing elective coronary angiography.
  • Statistical analysis to determine the significance of demographic and clinical factors on FFR utilization.

Main Results:

  • Overall FFR utilization was found to be 6.3% in the studied elderly population.
  • Age, sex, race, prior stress testing, and geographic region were significant predictors of FFR use.
  • Significant disparities in FFR adoption were observed based on these factors.

Conclusions:

  • FFR use in elderly patients undergoing elective coronary angiography remains low.
  • Multiple demographic and regional factors influence FFR adoption, highlighting barriers to widespread implementation.
  • Further research is needed to explore and overcome these barriers for broader FFR utilization.

Coronary Circulation01:21

Coronary Circulation

The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Subcellular Fractionation01:32

Subcellular Fractionation

The homogenate obtained after cell lysis contains various membrane-bound organelles that can be further separated into pure fractions by subcellular fractionation. These isolates are used to study specific cellular components, analyze localized protein activity, and are even employed in diagnostics. Fractionation is typically achieved using centrifugation methods, the most common being density-gradient and differential centrifugation.

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...

Mixtures of Gases: Dalton's Law of Partial Pressures and Mole Fractions

Unless individual gases chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each gas in a mixture exerts the same pressure that it would exert if it were present alone in the container. The pressure exerted by each individual gas in a mixture is called its partial pressure.

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,...

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
