Effects of Intracoronary Alteplase on Microvascular Function in Acute Myocardial Infarction

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Impaired microcirculatory reperfusion worsens prognosis following acute ST‐segment–elevation myocardial infarction. In the T‐TIME (A Trial of Low‐Dose Adjunctive Alteplase During Primary PCI) trial, microvascular obstruction on cardiovascular ...

Dynamic Single-Photon Emission Computed Tomography Data Analysis: Capabilities for Determining Functional Significance of Coronary Artery Atherosclerosis

MATEC Web of Conferences, 2016
The aim of the study was to develop the method for collecting and processing scintigraphic data to determine myocardial flow reserve by using gamma-camera with a new type detector based on Cadmium Zinc Telluride (CZT).

Coronary Collateral Circulation and Myocardial Blood Flow Reserve [PDF]

Circulation, 1972
This study was undertaken to assess the effect of collateral circulation on myocardial blood flow (MBF) reserve (ability to increase myocardial blood flow with a stress that increases myocardial oxygen requirements). One hundred patients had MBF measured at rest and after isoproterenol. After classification by anatomic severity of coronary

Effect of hypoglycaemia on measures of myocardial blood flow and myocardial injury in adults with and without type 1 diabetes: A prospective, randomised, open‐label, blinded endpoint, cross‐over study

Endocrinology, Diabetes & Metabolism, 2021
Aims This study examined the effect of experimentally‐induced hypoglycaemia on measures of myocardial blood flow and myocardial injury in adults with, and without, type 1 diabetes. Methods In a prospective, randomised, open‐label, blinded, endpoint cross‐

Comparison of myocardial contrast echocardiography derived myocardial perfusion reserve with invasive determination of coronary flow reserve [PDF]

European Journal of Echocardiography, 2008
Invasive measurements of coronary flow reserve (CFR) by Doppler flow wire are an established method for determining coronary blood flow physiology. Myocardial contrast echocardiography (MCE) is a potential non-invasive method for quantifying myocardial blood flow (MBF).

Reply: Clarifying the Utility of Myocardial Blood Flow and Myocardial Flow Reserve After Cardiac Transplantation [PDF]

Journal of Nuclear Medicine, 2019
REPLY: We would like to thank Dr. Sabour for taking an interest in our article, which highlights the potential diagnostic and prognostic utility of PET in patients after cardiac transplantation with known or suspected cardiac allograft vasculopathy (CAV) ([1][1]). As discussed by Dr.
