Point Biomedical Corp is developing PB-127 (CardioSphere) as an ultrasound imaging agent for assessing myocardial perfusion in patients with coronary artery disease. In January 2006, the company submitted an NDA for the agent; this was accepted for review in February 2006, with a Prescription Drug User Fee Act review and action date of late October 2006. PB-127 is effective for intermittent harmonic power Doppler imaging and may be the first contrast agent to receive FDA approval for myocardial perfusion imaging.

Background: High levels of catecholamines are cardiotoxic and associated with stress-induced cardiomyopathies. Septic patients are routinely exposed to endogenously released and exogenously administered catecholamines, which may alter cardiac function and perfusion causing ischemia. Early during human septic shock, left ventricular ejection fraction (LVEF) decreases but normalizes in survivors over 7-10 days.

As several decades of research have shown the cardioprotective effects of angiotensin-converting enzyme (ACE) inhibitors alone or in combination with diuretics, we were interested in investigating the effects of subchronic therapy of these drugs on ischemia-reperfusion (I/R) damage to the heart, as well as their influence on oxidative status. The research was conducted on 40 spontaneously hypertensive male Wistar Kyoto rats, divided into 4 groups. Animals were treated for four weeks with 10 mg/kg/day zofenopril alone or in combination with hydrochlorothiazide, indapamide and spironolactone per os.

Background: The majority of functional ischemia tests in patients with suspected chronic coronary syndromes (CCS) yield normal results. Implementing gatekeepers for patient preselection, such as pretest probability (PTP) and/or coronary artery calcium score (CACS), could reduce the number of normal scan results, radiation exposure and costs. However, the efficacy and safety of these approaches remain unclear.

Purpose: Research on the safety and efficacy of del Nido cardioplegia in adult patients with reduced left ventricular ejection fraction (LVEF) is limited. We evaluated the effect of del Nido cardioplegia on early outcomes of cardiac surgery in this cohort.
Methods: PubMed, Scopus, and the Cochrane Central Register of Controlled Trials were searched through August 2024 to conduct a meta-analysis comparing del Nido to other cardioplegia in adult patients with reduced LVEF (≤50%).

Ischemic heart disease is the leading cause of death worldwide. Reduced oxygen supply and myocardial hypoxia lead to tissue damage and impairment of the heart function. To the best of our knowledge, the primary functional effects of hypoxia in the multicellular model of living myocardial slices (LMSs) have not been investigated so far.
