Association between Multiplate-measured aspirin resistance and vitamin D deficiency in stable coronary artery disease.

Introduction: Insufficient inhibition of platelets in patients with atherosclerosis despite antiplatelet therapy leads to important clinical consequences. The present study evaluated the role of vitamin D (VD) deficiency in aspirin resistance (AR) in patients with stable coronary artery disease (CAD) treated with aspirin.

Material And Methods: This study included 70 patients with stable CAD who had been using 100 mg aspirin for at least seven days.

A Mysterious Crescent in the Heart: Ruptured Sinus of Valsalva Dissecting Interatrial Septum, Multimodality Imaging, and Full Recovery.

A 59-year-old man who was admitted to the emergency department with new and spontaneous onset of fatigue, dyspnea, and palpitations. There was neither a history of trauma, chest pain, nor infection. Transthoracic two- and three-dimensional echocardiography and computer tomography demonstrated sinus of Valsalva aneurysm rupture dissecting interatrial septum and leading to a huge thrombus formation in it.

Potential contribution of virtual histology plaque composition to hemodynamic-morphologic dissociation in patients with non-ST elevation acute coronary syndrome.

Objective: Histologic plaque characteristics may influence the hemodynamic effect generated by physiologically significant unstable coronary lesions where plaque content and surface related factors are expected to contribute to the maximum translesional pressure drop. In this study, we aimed to identify local lesion specific virtual histological characteristics that may potentially affect hemodynamic outcome measures.

Methods: Forty-eight consecutive patients with non-ST-elevation acute coronary syndrome (NSTEACS) having paired hemodynamic and morphological data were enrolled.
