まとめ
マイクロ軸流ポンプ(mAFP)は、標準治療と比較して、ST上昇型心筋梗塞および心原性ショック患者における出血イベントを増加させた。出血リスクは、機械的循環補助の複雑性とともに上昇し、半数は除去後に発生した。
科学分野:
- 循環器病学
- 介入循環器病学
- 機械的循環補助
背景:
- マイクロ軸流ポンプ(mAFP)は、心原性ショックを伴うST上昇型急性心筋梗塞(STEMI-CS)に対して有望である。
- mAFPの使用は出血イベントの増加と関連しており、さらなる調査が必要である。
主な方法:
- DanGer Shock試験では、355人のSTEMI-CS患者をmAFP群または標準治療群に無作為に割り付けた。
- 出血は、出血アカデミックリサーチコンソーシアム(BARC)タイプ3-5を使用して分類された。
- フォローアップには、MCS使用中および使用後の出血の評価が含まれた。
結論:
- mAFPを受けた患者は、標準治療を受けた患者よりも重度の出血を経験した。
- 出血イベントはMCSの複雑性と関連しており、デバイス除去後に頻繁に発生した。

Shock Waves

While deriving the Doppler formula for the observed frequency of a sound wave, it is assumed that the speed of sound in the medium is greater than the source's speed through it. When this condition is breached, a shock wave occurs.
When the source's speed approaches the speed of sound, constructive interference between successive wavefronts emitted by the source occurs immediately behind it. Initially, scientists believed that this constructive interference would result in such high...

Blood Pressure Imbalances and Circulatory Shock
1.7K
Disorders affecting blood volume, vascular tone, or vascular function can disrupt vascular homeostasis, including conditions like hypertension, hemorrhage, and shock.
Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...

Bleeding in Fresh Concrete
616
Bleeding in fresh concrete occurs when water from the mix rises to the surface. This happens because the mix's solid components fail to retain all the water as they settle, leading to separation where water collects at the top. The severity of bleeding can be measured by assessing the total settlement or by noting the decrease in height per unit height of concrete.
Bleeding can cause several issues in the concrete structure. Sometimes, the rising water gets trapped beneath large aggregate...

Patient-centered Care
3.1K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Drug Dosing: Geriatric Patients
278
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Drug Dosing: Obese Patients
269
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...
