Insights

Percutaneous coronary intervention (PCI) is safe for elderly patients in Thailand. Advanced age did not predict in-hospital mortality, though elderly patients experienced higher complication rates.

Area of Science:

  • Cardiology
  • Geriatric Medicine
  • Health Outcomes Research

Background:

  • Percutaneous coronary intervention (PCI) is a common procedure for coronary artery disease.
  • Elderly patients often present with more comorbidities, potentially impacting PCI outcomes.
  • Understanding mortality risk factors in this demographic is crucial for clinical decision-making.

Purpose of the Study:

  • To assess the outcomes of PCI in elderly patients in Thailand.
  • To identify risk factors associated with in-hospital mortality in this population.

Main Methods:

  • Retrospective analysis of 4,156 patients undergoing PCI (May 2006 - October 2007).
  • Comparison of outcomes between elderly (≥75 years) and non-elderly (<75 years) groups.
  • Multivariate analysis to identify predictors of in-hospital mortality.

Main Results:

  • Elderly patients had lower PCI success rates (87.5% vs 91.2%) and higher rates of renal failure (3.9% vs 1.8%) and Q-wave myocardial infarction (3.0% vs 1.4%).
  • Unadjusted in-hospital mortality was higher in elderly patients (5.3% vs 2.4%).
  • Acute coronary syndrome and heart failure were significant predictors of mortality; advanced age was not (OR=1.37, p=0.174).

Conclusions:

  • PCI is a safe and effective procedure for elderly patients in Thailand.
  • Advanced age itself is not a significant predictor of in-hospital mortality after PCI.
  • Focusing on comorbidities like acute coronary syndrome and heart failure is key for risk stratification.

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...

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...

Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

Acute Coronary Syndrome IV: Interprofessional Care

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...
Pharmacodynamics in Geriatric Patients: Effects of Age01:27

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...
