The PRECISE-DAPT score

Area of Science:

  • Cardiology
  • Clinical Research
  • Predictive Analytics

Background:

  • The PRECISE-DAPT score predicts bleeding risk after percutaneous coronary intervention (PCI).
  • Its predictive ability may change over time and differ between sexes.
  • Understanding these dynamics is crucial for patient management.

Purpose of the Study:

  • To compare the predictive performance of the PRECISE-DAPT score at baseline versus during follow-up in male and female patients after PCI.
  • To assess how the score's ability to predict bleeding events evolves over time.

Main Methods:

  • Prospective, multicenter RE-SCORE registry.
  • Inclusion of 480 patients undergoing PCI and treated with 1-year dual antiplatelet therapy (DAPT).
  • Calculation of PRECISE-DAPT score at baseline and at 1, 4, and 8-month follow-ups.

Main Results:

  • Baseline PRECISE-DAPT scores were similar between males and females.
  • Increases in PRECISE-DAPT scores were significantly more frequent in females (44%) than males (23%).
  • Follow-up reassessment showed excellent bleeding prediction in females (c-index=0.84) but modest prediction in males (c-index=0.61).

Conclusions:

  • The bleeding predictive ability of the PRECISE-DAPT score varies over time, particularly in females.
  • Reassessing the PRECISE-DAPT score during follow-up improves its discriminative ability in females, while remaining modest in males.
  • Sex-specific monitoring of bleeding risk post-PCI is warranted.

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...

Venous Thrombosis IV: Nursing Management

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration.

Disorders of Hemostasis01:24

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Formation of the Platelet Plug01:22

Formation of the Platelet Plug

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
