Outcomes after stenting of renal artery stenosis in patients with high-risk clinical features.

Background: In patients with renal artery stenosis, revascularization was seen as a mean to improve outcomes, but large studies failed to show significant benefit in general population. However, data on benefits of renal artery stenting in patients with high-risk features, such as rapidly declining renal function and cardiac destabilization syndromes, are limited, as they were excluded from trials. In this descriptive study, we aimed to evaluate short- and long-term outcomes in high-risk patients with renal artery stenosis, treated by angioplasty and stenting.

Intravascular ultrasound insights into the unstable features of the coronary atherosclerotic plaques: A systematic review and meta-analysis.

Background: There is a lack of a comprehensive picture of plaque geometry and composition of unstable atherosclerotic lesions as observed with intravascular ultrasound techniques. We analysed through a systematic review with meta-analysis 39 characteristics of atherosclerotic plaques in three scenarios involving culprit and non-culprit lesions from acute coronary syndromes vs stable angina pectoris patients, and culprit vs non-culprit lesions in acute coronary syndromes patients.

Methods: A systematic search of PubMed and EMBASE, from inception to April 2020 was performed.

Takotsubo Cardiomyopathy presenting as ST-elevation myocardial infarction: wide triggering spectrum and specific echocardiographical pattern in a consecutive case series report.

We report a series of six consecutive cases of Takotsubo Cardiomyopathy (TCM) presenting as ST-elevation acute myocardial infarction and consequently addressed to the emergency coronary angiography, inside a time-frame of one year (2015). This series underlines the wide possible triggering spectrum and clinical severity of TCM and recognizes echocardiography as an essential imaging technique in the diagnosis due to its widespread availability and feasibility in the acute care setting.
