Desde noviembre de 1988 hasta mayo de 1992, 108 pacientes (79 hombres, 29 mujeres) de 75 años o más (media 78 +/- 3, rango 75-90 años) se sometieron a una angioplastia coronaria (grupo I: n = 62) o a una cirugía de bypass coronario (grupo II: n = 46). Los pacientes del grupo II eran más jóvenes (76 +/- 2 frente a 79 +/- 4, P = 0,002) y presentaban una mayor proporción de enfermedad multivaso. Ambos grupos eran comparables con respecto a la presencia de angina inestable, la fracción de eyección del ventrículo izquierdo y el infarto con onda Q. La mortalidad intrahospitalaria fue similar en los dos grupos (6,4% frente a 4,3%). La revascularización completa (72% frente a 47%, P < 0,05) y la revascularización de la arteria descendente anterior izquierda (100% frente a 45%, P < 0,01) fueron más frecuentes en el grupo II. La supervivencia libre de infarto a los dos años fue similar (grupo I: 76 +/- 6%; grupo II: 79 +/- 6%), pero la angina recurrente de clase III o IV (36% frente a 9%, P < 0,05) y la repetición de procedimientos (26% frente a 0%, P < 0,05) fueron más frecuentes en el grupo I.

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Coronary Artery Disease V: Interprofessional Care

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

Angina IV: Management

IntroductionThe management of angina requires a comprehensive approach that includes pharmacological therapies, medical procedures, and lifestyle modifications.Pharmacological TherapiesAntiplatelet agents, such as aspirin, clopidogrel, prasugrel, and ticagrelor, play a pivotal role in preventing thrombus formation in patients with angina. These medications inhibit platelet aggregation and reduce the likelihood of myocardial infarction and other cardiovascular events.Anticoagulants, including...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
