Infrapopliteal arterial occlusive disease in elderly men: a population based study
1Vascular Surgery Department, Hospital del Mar, Barcelona, Spain. aclara@imas.imim.es
Summary
Isolated infrapopliteal arterial disease is common in older men and linked to coronary heart disease (CHD). This condition, often asymptomatic, shares risk factors like smoking and diabetes with CHD.
Area of Science:
- Vascular Medicine
- Cardiology
- Epidemiology
Background:
- Peripheral arterial occlusive disease (PAOD) affects older adults.
- Infrapopliteal arterial disease is a specific manifestation of PAOD.
- Understanding its prevalence and associations is crucial for cardiovascular health.
Purpose of the Study:
- To determine the prevalence of isolated infrapopliteal PAOD in older men.
- To identify associated cardiovascular risk factors.
- To investigate the link between isolated infrapopliteal PAOD and coronary heart disease (CHD).
Main Methods:
- Cross-sectional study of 699 men aged 55-74.
- Collected data on cardiovascular history and risk factors.
- Utilized electrocardiogram and lower limb segmental pressures/waveforms.
Main Results:
- PAOD found in 13.4% of subjects; 39.4% had isolated infrapopliteal PAOD.
- Isolated infrapopliteal PAOD associated with older age, smoking, diabetes, and hypertriglyceridemia.
- Significant association (OR 1.8-3.4) between PAOD and CHD, regardless of PAOD pattern.
Conclusions:
- Isolated infrapopliteal PAOD is a frequent, often asymptomatic, condition in older men.
- It is strongly associated with both symptomatic and asymptomatic CHD.
- Risk factor profile differs from extended PAOD, primarily in smoking and lipid profile.

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:30Peripheral Artery Disease I: Introduction
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
01:27Peripheral 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...
01:27Pharmacodynamics 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...
01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are not...
01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
