Coronary Artery Calcium and Aging: Physiological Basis, Assessment, and Treatment Options in Percutaneous Coronary Intervention.

Coronary artery calcification is a complex anatomical and histological pathology with different pathways that contribute to calcium deposit and calcification progression. As part of the atherosclerotic process, extensive calcifications are becoming more common and are associated with poorer PCI outcomes if not properly addressed. Since no drug has shown to be effective in changing this process once it is started, proper knowledge of the underlying pathogenesis and how to diagnose and manage it is essential in contemporary coronary intervention.

Assessing nature exposure: a study on the reliability and validity of a Portuguese version of the nature exposure scale.

Introduction: Engaging with nature has been widely acknowledged for its positive impact on well-being. Traditionally, assessments of nature exposure focus on estimating green space exposure and outdoor time. However, the Nature Exposure Scale (NES) offers a unique approach by evaluating the quality of nature experiences, encompassing both deliberate and spontaneous encounters.

[Cardiac arrest caused by anomalous origin and course of the right coronary artery].

The anomalous origin of the right coronary artery from the left sinus with interarterial course is a rare but life-threatening coronary abnormality. Coronary computed tomography is crucial in identifying this disease whose treatment, based on coronary artery bypass grafting, is recommended in symptomatic patients but is more controversial in asymptomatic patients. The case report presented offers an opportunity to discuss the pathophysiological, diagnostic and therapeutic aspects of this congenital coronary artery disease.
