概括
致病性肥胖症并不排除患者接受微创性大动脉置换 (MIAVR). 部分上部迷宫切除术对于接受MIAVR的肥胖患者来说是一种安全有效的方法,可以在不影响安全的情况下促进恢复.
科学领域:
- 心血管外科心血管外科
- 最少侵入性的心脏手术
- 肥胖医学 肥胖医学
背景情况:
- 致病性肥胖症在心脏手术中带来了挑战,导致一些人认为微创性大动脉置换 (MIAVR) 是相对的禁忌.
- 关于MIAVR在致病性肥胖患者的安全性和有效性的证据有限,尽管它在标准风险人群中越来越多地使用.
研究的目的:
- 评估MIAVR在致病性肥胖患者中的安全性和有效性.
- 为了比较MIAVR的结果通过部分上部 ministernotomy在肥胖与非肥胖患者.
- 评估肥胖作为MIAVR后不良结果的预测因素的作用.
主要方法:
- 对920名通过部分上部迷宫切除术接受MIAVR的患者进行了回顾性队列研究.
- 患者被分为I类肥胖 (BMI 30-35 kg/m2),II-III类肥胖 (BMI >35 kg/m2) 和非肥胖的组.
- 临床结果,心声学参数,术后并发症和死亡率的比较. 对肥胖患者的MIAVR与常规椎切除术的对对元分析.
主要成果:
- 在大多数手术后的结果中,肥胖和非肥胖群体之间没有显著的差异.
- 在II-III类肥胖症中观察到较高的肺胸部和心律失常率.
- 肥胖不是不良结果的独立预测因素;元分析显示,与MIAVR.具有相似的手术时间和更短的ICU停留时间/更少的呼吸道并发症.
结论:
- 仅仅肥胖不应该阻止合适的候选人接受大动脉置换手术.
- 部分上部迷宫切除术是接受MIAVR的肥胖患者的首选接入途径,可以在不影响安全的情况下促进恢复.

Drug Dosing: Obese Patients
263
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution
282
Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion
184
Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

Obesity
1.3K
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Analysis of Population Pharmacokinetic Data
753
Analysis of population pharmacokinetic data involves studying the behavior of drugs within diverse populations to understand their pharmacokinetic parameters. Traditional pharmacokinetic methods typically involve collecting samples from a few individuals and estimating these parameters. While these methods are commonly used, they have limitations in capturing the variability in drug response among individuals or heterogeneous populations. Population pharmacokinetics is employed to address these...

Heart Valves
12.1K
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
