Antianginal Drugs: Calcium Channel Blockers and Ranolazine01:25

Antianginal Drugs: Calcium Channel Blockers and Ranolazine

462
Angina pectoris, a primary symptom of ischemic heart disease, requires careful pharmacological interventions. In this context, calcium channel blockers (CCBs) and ranolazine have emerged as crucial pharmacotherapeutic agents, providing deep insights into the complexities of angina management.
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

146
Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

Antianginal Drugs: Nitrates and β-Blockers

540
In cardiovascular health, antianginal drugs combat angina pectoris — a condition marked by chest pain owing to diminished blood flow to the heart.
Organic nitrates,  such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Devices

Background:

  • Eruptive calcified nodules (CNs) represent severely calcified plaques in coronary lesions.
  • These plaques are associated with both acute coronary syndrome (ACS) and non-ACS conditions.
  • Optical coherence tomography (OCT) is vital for diagnosing and guiding treatment of CNs.

Purpose of the Study:

  • To review current management strategies for eruptive calcified nodules.
  • To highlight recent technological advancements in treating these challenging lesions.
  • To provide guidance on selecting appropriate treatment modalities.

Main Methods:

  • Review of current literature on eruptive calcified nodules and their treatment.
  • Discussion of advanced interventional techniques, including intravascular lithotripsy, excimer laser coronary atherectomy, rotational atherectomy, and orbital atherectomy.
  • Analysis of factors influencing treatment selection.

Main Results:

  • Various treatment modalities have demonstrated effectiveness in managing eruptive CNs.
  • Intravascular lithotripsy, laser atherectomy, and rotational/orbital atherectomy are key advancements.
  • Treatment success depends on specific lesion characteristics and patient presentation.

Conclusions:

  • Management of eruptive CNs remains a significant challenge for interventional cardiologists.
  • A range of advanced devices are available, offering effective solutions.
  • Optimal device selection requires careful consideration of guidewire position, lesion characteristics, clinical context, and operator expertise.
