概括
液动力学再通道化 (HDR) 是一种用于冠状动脉慢性全封闭 (CTO) 的新技术. 虽然HDR用于复杂的病变,但与标准CTO穿皮冠状动脉干预 (PCI) 相比,它显示出较低的技术成功,但类似的主要不良心脏事件 (MACE).
科学领域:
- 心血管干预 心血管干预
- 干预心脏病学 干预心脏病学
- 血管接入技术 血管接入技术
背景情况:
- 水力动力回路 (HDR) 是一种先进的技术,用于穿越冠状动脉慢性全闭塞 (CTOs).
- 这种方法涉及到内对比注射和在聚合物外套内向导线的推进.
- 它代表了复杂的冠状动脉干预的新方法.
研究的目的:
- 为了比较CTO通过皮肤冠状动脉干预 (PCI) 的技术和程序结果,使用HDR和没有HDR进行.

Nursing Interventions I: Taxonomy of Nursing Interventions
3.9K
Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

Nursing Interventions II: Selecting and Classifying the Nursing Interventions
3.4K
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:

Coronary Circulation
7.4K
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Tumor Progression
7.5K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Operant Conditioning Intervention
515
Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
