Association between change in heart rate over years and life span in the Paris Prospective 1, the Whitehall 1, and Framingham studies.

Heart rate, a measure of the frequency of the cardiac cycle, reflects the health of the cardiovascular system, metabolic rate, and activity of the autonomic nervous system. Whether changes in resting heart rate are related to lifespan has not yet been explored to our best knowledge. In this study, we examined the association between resting heart rate and lifespan using linear regression in the Paris Prospective Study I, the Whitehall I Study, and the Framingham Heart Study.

[Coronary sinus reducer : Technical aspects, prevention and management of potential complications].

Coronary sinus reducer implantation is a percutaneous technique creating a narrowing in the coronary sinus through the implantation of an hourglass-shaped endoprosthesis. It is proposed to reduce symptoms in patients suffering from refractory angina pectoris. This innovative treatment is experiencing a major craze among interventional cardiologists.

[How to solve difficult side branch access: case report and literature review].

We present the case of a 53-year-old patient with history of hypertension and dyslipidemia, admitted for effort-induced angina. Coronary angiography revealed two-vessel disease with severe stenosis of the LAD- Diagonal bifurcation (MEDINA 1-1-1). This lesion was considered complex regarding the severe stenosis of the bifurcation core, the angulation <45°, and the severity and length of the diagonal lesion.

An entrapped undeflatable coronary balloon is a rare complication during percutaneous coronary intervention. It is a complication that can be stressful for the operator, with potentially catastrophic implications for the patient. A fully inflated balloon in the coronaries impedes the blood flow to the distal myocardium and hence causes ischemia, that could jeopardize the hemodynamics of the patients and potentially lead to life-threatening complications.
