Unstable angina is a clinical diagnosis that may present with or without electrocardiographic changes. The "giant R wave" on electrocardiogram has been reported as a manifestation of acute ischemia; however, it is a rare finding in current clinical practice. We describe a case of a patient with unstable angina and a transient "giant R wave" pattern with a culprit lesion in the right coronary artery.

Background: Switching from a conventional to a high-sensitivity cardiac troponin (hs-cTn) assay enables detection of smaller amounts of myocardial damage, but the clinical benefit is unclear. We investigated whether switching to a hs-cTnI assay with a sex-specific 99th centile diagnostic threshold was associated with lower 1-year death or new myocardial infarction (MI) in patients with suspected acute coronary syndrome (ACS).

Methods: This pre-post study included nine tertiary hospitals in Australia.

Background: The effect of worsening renal function and baseline chronic kidney disease (CKD) on outcomes in patients with chronic coronary syndrome in the setting of optimal medical therapy remains unknown.

Methods And Results: The REAL-CAD (Randomized Evaluation of Aggressive or Moderate Lipid Lowering Therapy With Pitavastatin in Coronary Artery Disease) study is a prospective, multicenter, randomized trial of high-dose (pitavastatin 4 mg/day) or low-dose (pitavastatin 1 mg/day) statin therapy in 12 118 patients with chronic coronary syndrome. The primary end point was a composite of cardiovascular death, nonfatal myocardial infarction, stroke, or unstable angina requiring hospitalization (major adverse cardiac and cerebral events [MACCE]).

Background: Proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibodies (mAbs) have demonstrated promising effects in lowering cardiovascular incidents among patients with acute coronary syndrome. However, their influence on early platelet reactivity after primary percutaneous coronary intervention (PPCI) remains unclear.

Objectives: This research sought to investigate the effects of entirely human anti-PCSK9 antibodies on platelet function as measured by thrombelastography and 12-month postoperative results in patients receiving PPCI and treated with ticagrelor-based dual antiplatelet therapy.

Objectives: The aim of this study was to investigate the expression characteristics and interrelationships of FNDC5 and pyroptosis-associated molecules in peripheral blood mononuclear cells of patients with coronary heart disease (CHD).

Methods: Patients were divided into stable angina (SA), unstable angina (UA), and acute myocardial infarction (AMI) groups based on different clinical symptoms. According to the Gensini score, they were then divided into mild, moderate, and severe lesion groups.

Peak Procedural ACT Is Associated With All-Cause Mortality After Femoral Access PCI.

J Soc Cardiovasc Angiogr Interv

December 2024

Division of Cardiovascular Medicine, Sulpizio Cardiovascular Center, University of California San Diego, San Diego, California.

Background: A minimum threshold activated clotting time (ACT) to guide heparin dosing during percutaneous coronary intervention (PCI) is associated with lower ischemic complications. However, data are variable regarding the risk of high ACT levels. The aim of this study was to assess the impact of peak procedural ACT on complications and mortality for transfemoral and transradial access PCI.
