Cannabinoids are compounds which were first isolated from the Cannabis sativa plant. For thousands of years they have been used for treatment of numerous diseases. Currently, synthetic cannabinoids and endocannabinoids are also known. Cannabinoid receptors, endocannabinoids and the enzymes that catalyze their synthesis and degradation constitute the endocannabinoid system which plays an important role in functioning of the cardiovascular system. The results obtained to date suggest the involvement of endocannabinoids in the pathology of many cardiovascular diseases, including myocardial infarction, hypertension and hypotension associated with hemorrhagic, endotoxic, and cardiogenic shock. Cardioprotective effect and dilation of coronary vessels induced by endocannabinoids deserve special attention. It cannot be excluded now that in the future our better understanding of cannabinoid system will allow to develop new strategies for treatment of cardiovascular diseases.

Catlet scoring system as a new predictor for in-stent restenosis in patients with chronic coronary artery disease undergoing percutaneous coronary intervention with drug-eluting stent.

Background: He's team have recently developed a new Coronary Artery Tree description and Lesion EvaluaTion (CatLet) angiographic scoring system, which is capable of accounting for the variability in coronary anatomy, and risk-stratifying patients with coronary artery disease. Preliminary studies have demonstrated its superiority over the the Synergy between percutaneous coronary intervention with Taxus and Cardiac Surgery (SYNTAX) score with respect to outcome predictions for acute myocardial infarction (AMI) patients. However, there are fewer studies on the prognostic in chronic coronary artery disease(CAD).

Cardiomyocytes can be implanted to remuscularize the failing heart. Challenges include sufficient cardiomyocyte retention for a sustainable therapeutic impact without intolerable side effects, such as arrhythmia and tumour growth. We investigated the hypothesis that epicardial engineered heart muscle (EHM) allografts from induced pluripotent stem cell-derived cardiomyocytes and stromal cells structurally and functionally remuscularize the chronically failing heart without limiting side effects in rhesus macaques.

Acute myocardial infarction (AMI) remains one of the most common causes for cardiogenic shock (CS), with high inpatient mortality (40-50 %). Studies have reported the use of pulmonary artery catheters (PACs) in decompensated heart failure, but contemporary data on their use to guide management of AMI-CS and in different SCAI stages of CS are lacking. We investigated the association of PACs and clinical outcomes in AMI-CS.

The homeostasis model assessment of β-cell function (HOMA-β) measures pancreatic β-cell function. This study investigated the association between HOMA-β and adverse cardiovascular events in non-diabetic CVD patients.

Background: The association between coronary microcirculation and clinical outcomes in patients with intermediate stenosis remains unclear.
Objectives: The aim of this study was to assess the prognostic significance of angiography-derived index of microcirculatory resistance (angio-IMR) in patients with intermediate coronary stenosis.
Methods: This post hoc analysis included 1,658 patients from the FLAVOUR (Fractional Flow Reserve and Intravascular Ultrasound for Clinical Outcomes in Patients with Intermediate Stenosis) trial, with angio-IMR measured in each vessel exhibiting intermediate stenosis.
