本文主要讲述的是PCI技术的应用，应用PCI技术的关键原因之一是治疗STEMI和急性心肌梗死。STEMI的治疗可以通过对PCI服务的充分投资来发展，需要维持一个由心脏病专家组成的集群。香港的医院也可以被看作是提供PCI治疗STEMI的扩展服务，尽管它们的效率取决于国内医疗行业的基础设施(医院管理局，2013)。Ng & Graham(2011)提到，香港的主要PCI服务正面临与STEMI相关的问题。本篇利兹市论文代写文章由英国论文通AssignmentPass辅导网整理，供大家参考阅读。
One of the key causes of using PCI technique is to treat the patients suffering from STEMI and acute myocardial infarction. Treatment of STEMI can be developed by means of sufficient investments in the PCI services, with a need to maintain a cluster that consists of expert cardiologists. The hospitals in Hong Kong can also be observed as engaged in providing extended services of PCI for treatment of STEMI, although their efficiency is subjected to the infrastructure of the domestic healthcare industry (Hospital Authority, 2013). Ng & Graham (2011) mentions that primary PCI services in Hong Kong are facing issues particularly related to STEMI.
It has also been observed that patients lack access to the required information so that they can gain knowledge about their health conditions and take precautionary measures to prevent any complication associated with the treatment process. The hospitals in Hong Kong often also lack the ability to offer primary PCCI on a 24/7 basis to the patients with chronic cardiac problems, while most of the patients are observed to be treated by means of thrombolysis instead of primary PCIs (Ng & Graham, 2011). In the views of Cheung et al. (2010) and Wu et al. (2012), primary PCI is more advantageous than thrombolysis because it is useful in reducing the number of deaths, ischaemia, stroke and blockage of the artery. Despite such advantages, use of thrombolytic therapy has been used at a larger scale in Hong Kong than primary PCI (Cheung et al., 2010).
Correspondingly, Lee (2008) opined that during PCI, coronary stents are used in hospitals, following the guidelines noted by the Hospital Authority of Hong Kong. The guidelines denote that PCIs can be conducted through the use of stents and balloons, as deemed less risky for angioplasty that might differ from patient to patient. However, the use of coronary stents has led to certain problems due to repeated revascularization needs, as in majority cases, bare stents of metal are used for PCIs. Improvement were possible with the use of drug eluting stents that were useful in the delivery of anti-proliferative drugs to the affected artery by means of a polymer, as present on the surface of the stent. Use of this method helped reducing the risk of restenosis but has remained subjected to the quality of care provided during the post PCI session (Lee, 2008).
