1988年11月から1992年5月まで、75歳以上の患者108名(男性79名、女性29名、平均年齢78 ± 3歳、範囲75~90歳)に対し、冠動脈形成術(グループI:n = 62)または冠動脈バイパス術(グループII:n = 46)を実施した。グループIIの患者は、グループIよりも若く(76 ± 2歳 vs 79 ± 4歳、P = 0.002)、多枝疾患の割合が高かった。不安定狭心症の有無、左室駆出率、およびQ波心筋梗塞に関しては、両群間で同等であった。院内死亡率は両群で同様であった(6.4% vs 4.3%)。完全血行再建(72% vs 47%, P < 0.05)および左前下行枝の血行再建(100% vs 45%, P < 0.01)は、グループIIでより頻繁に認められた。2年心筋梗塞不発生生存率は同等であったが(グループI:76 ± 6%、グループII:79 ± 6%)、再発性のクラスIIIまたはIVの狭心症(36% vs 9%, P < 0.05)および再手術(26% vs 0%, P < 0.05)は、グループIでより頻繁に認められた。

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...

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...
