coronary blood flow


Also found in: Acronyms.

coronary blood flow

The amount of blood perfusing the heart muscle through the coronary arteries. This may be measured by one of several techniques including indicator dilution or use of radioisotopes.

Among them are the fact that capsaicin is believed to play a role in cellular and molecular mechanisms that prevent obesity and modulate coronary blood flow, and also possesses antimicrobial properties that "may indirectly affect the host by altering the gut microbiota."
It then uses computer algorithms to simulate blood flow and assess the impact of blockages on coronary blood flow.
Then, HeartFlow leverages deep learning to create a personalized, digital 3D model of the patient's coronary arteries and uses powerful computer algorithms to solve millions of complex equations to simulate blood flow in the model and assess the impact of blockages on coronary blood flow. The results are provided to the patient's clinician via a secure web interface to offer actionable information on the optimal course of treatment.
Numbers of toxic substances produce myocardial injury independent of interruption in coronary blood flow. It includes biogenic amines and drugs like anthracyclines.
A PCI procedure, or coronary angioplasty, is a non-surgical procedure designed to open coronary blood flow blockages and restore blood flow to the hearts of patients living with coronary artery disease (CAD).

Hypotensive anesthesia may substantially decrease coronary blood flow. However it simultaneously decreases myocardial oxygen demand, due to the reduction in afterload (usually) and/or preload (sometimes).
