Insights

For older patients with atrial fibrillation (AF) and coronary artery disease needing stenting, triple therapy increases bleeding risk. Alternative treatments show promise for improved safety in this complex patient group.

Area of Science:

  • Cardiology
  • Pharmacology
  • Geriatrics

Background:

  • Atrial fibrillation (AF) and coronary artery disease (CAD) frequently coexist in elderly patients.
  • Percutaneous coronary intervention (PCI) with stenting is a common treatment for CAD.
  • Concurrent anticoagulation and dual antiplatelet therapy (triple therapy) is often required, posing significant bleeding risks.

Purpose of the Study:

  • To review evidence comparing triple therapy with alternative regimens in AF patients undergoing PCI.
  • To assess the safety and efficacy of different therapeutic strategies.

Main Methods:

  • Systematic review of randomized clinical trials and observational studies.
  • Comparison of triple therapy against various alternative treatment options.
  • Focus on bleeding risk and therapeutic outcomes.

Main Results:

  • Current guidelines recommend triple therapy, particularly in acute coronary syndrome (ACS).
  • Triple therapy is associated with an excessive risk of bleeding.
  • Alternative regimens to triple therapy demonstrate promising safety profiles.

Conclusions:

  • While evidence is not exhaustive, alternative strategies to triple therapy in AF patients undergoing PCI are encouraging.
  • Further research is crucial to establish optimal, safer treatment protocols.
  • Balancing antithrombotic efficacy and bleeding risk remains a key challenge.

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

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...

AC Sources01:20

AC Sources

Direct current is a flow of electric charge in only one direction and has a steady state of constant voltage in the circuit. Rectifiers, batteries, commutator-equipped generators, and fuel cells are some examples of devices that generate direct current. Nowadays, most applications use a time-varying voltage source. Alternating current is a flow of electric charge that periodically reverses direction. An alternating current is produced by an alternating emf that is generated in a power plant. If...

Resistor in an AC Circuit

An alternating emf or voltage source is needed to supply an alternating current (AC) to a circuit. A coil of wire rotating in a magnetic field at a constant angular speed represents such a source. It also generates a sinusoidal alternating emf and serves as an industrial alternator.
One-way current through the meter is measured using diodes. A diode is a device with better conductivity in one direction compared to the other; in its ideal state, it has zero resistance in one direction and allows...

Power in an AC Circuit01:26

Power in an AC Circuit

In a DC circuit, the power consumed is simply the product of the DC voltage times the DC current, given in watts. However, the power consumed for AC circuits with reactive components is calculated differently. Since electrical power is the "rate" at which energy is used in a circuit, all electrical and electronic components and devices have a safe operating range for electrical power.
In a DC circuit, there is no sinusoidal waveform associated with the supply; the voltages and currents are...
