Unstable Angina [PDF]

Circulation, 1998
Unstable angina results from an imbalance between myocardial oxygen supply and demand. Probably the most common cause is reduced myocardial perfusion resulting from a nonocclusive thrombus on a fissured or eroded atherosclerotic plaque that often had caused only mild to moderate obstruction previously.3 Nonocclusive thrombi in patients with unstable ...

Association of the 894G>T polymorphism of the endothelial constitutive nitric oxide synthase gene with unstable angina

Brazilian Journal of Medical and Biological Research, 2007
The 894G>T polymorphism of the endothelial constitutive nitric oxide synthase gene consists of the substitution of a guanine base by a thymine at the 894th nucleotide of the gene. An association of this polymorphism with acute coronary syndromes has been

Microaxial Flow Pump Support as a Bridge to Transaxillary TAVI‐In‐TAVI in Cardiogenic Shock

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT A 79‐year‐old man presented with cardiogenic shock due to severe degeneration of a prior transcatheter aortic valve. Temporary mechanical circulatory support with a transvalvular microaxial flow pump was initiated, resulting in rapid stabilization.

A Therapeutic Dilemma: Catastrophic ST‐Elevation Myocardial Infarction Following Antiplatelet Therapy Interruption in a Patient With JAK2‐Positive Polycythemia Vera

Clinical Case Reports, Volume 14, Issue 8, August 2026.
Premature interruption of dual antiplatelet therapy in a patient with polycythemia vera and clinically suspected acquired von Willebrand syndrome triggered catastrophic recurrent stent thrombosis, whereas perioperative bridging with eptifibatide enabled safe surgery. ABSTRACT Polycythemia vera is associated with a thrombotic–hemorrhagic paradox.

The Association between Hypoperfused Myocardium and Systolic Function in Patients With AMI Undergoing Complete Revascularization

Clinical Cardiology, Volume 49, Issue 8, August 2026.
Hypoperfused myocardium was detected in portions of acute myocardial infarction patients undergoing complete revascularization by hybrid positron emission tomography/magnetic resonance at 2 months. Patients with hypoperfused myocardium (Group A) had higher hs‐CRP and lower T2 values than those without (Group B). The reversal of myocardial perfusion was

Ativação plaquetária em formas clínicas distintas da doença arterial coronariana (papel da P-selectina e de outros marcadores nas anginas estável e instável) Platelet activation in different clinical forms of the coronary artery disease (roll of P-selectin and others platelet markers in the stable and unstable angina)

Arquivos Brasileiros de Cardiologia, 2006
OBJETIVO: Os marcadores da ativação plaquetária em geral se apresentam elevados na doença arterial coronariana. Desse modo, procuramos identificar a presença e as potenciais associações de diferentes marcadores da ativação plaquetária. MÉTODOS: Estudamos

Extracellular Vesicle cystatin c is associated with unstable angina in troponin negative patients with acute chest pain.

PLoS ONE, 2020
BackgroundDespite the use of high-sensitive cardiac troponin there remains a group of high-sensitive cardiac troponin negative patients with unstable angina with a non-neglectable risk for future adverse cardiovascular events, emphasising the need for ...

Impact of CYP2C19 and CYP3A4 Inhibitor Use on Clopidogrel Clinical Effectiveness in CYP2C19 Genotyped Patients Undergoing Percutaneous Coronary Intervention

Clinical Pharmacology &Therapeutics, Volume 120, Issue 2, Page 531-541, August 2026.
CYP2C19 and CYP3A4 contribute to clopidogrel bioactivation. CYP2C19 no‐function alleles diminish clopidogrel's antiplatelet effects and clinical effectiveness. Coadministration of either a CYP2C19 or a CYP3A4 inhibitor may also reduce clopidogrel's antiplatelet effects and lead to phenoconversion in patients without a CYP2C19 no‐function allele (normal/
