Abstract

BACKGROUND The aim of this study was to investigate the optimal route of administration of diltiazem in emergency PCI and to provide the best clinical treatment for ASTEMI patients. MATERIAL AND METHODS A total of 90 patients with ASTEMI treated in our hospital from January 2015 to January 2016 were selected. Prior to thrombus aspiration, a thrombus aspiration catheter was used to perform diltiazem injection at the distal end of the infarct-related artery (IRA). We chose the acute ST-elevation myocardial infarction (ASTEMI) patients treated with direct PCI to compare different administration routes of diltiazem. The occurrence of major adverse cardiac events (MACEs) was closely observed during hospitalization and was obtained through outpatient visits or telephone follow-ups over the next 6 months. RESULTS Intracoronary infusion of diltiazem at the distal end of the culprit vessel, compared to conventional coronary mouth and intravenous injection, was significantly improved in thrombolysis in myocardial infarction (TIMI) frame count immediately after PCI stent implantation, ST-segment drop rate after 90 min, and left ventricular ejection fraction (LVEF) after 1 week. Furthermore, the peak value of high-sensitivity cardiac tropo...Continue Reading

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis.
