Implementation of NICE clinical guideline 95 on chest pain of recent onset: experience in a district general hospital.

The National Institute for Health and Care Excellence (NICE) CG95 clinical guideline on chest pain of recent onset was published in 2010. There is debate over whether the proposed strategy improves patient care and its implications on service costs. Following a six-month pilot, 472 consecutive patient records were audited for pre-test probability of significant coronary artery disease, investigations performed and outcomes. Low- and moderate-risk patients had an unexpectedly low rate of coronary disease and revascularisation. Computerised tomography coronary angiography (CTCA) and stress echocardiography performed similarly, though the latter was more resource intensive. High-/very high-risk patients frequently required revascularisation and greater than 10% of each group had prognostically significant disease, going against the recommendation that very high risk patients do not undergo angiography. There were frequent protocol deviations and training clinic staff in the new approach was challenging. In conclusion, implementing NICE CG95 is feasible but presents challenges. Staff require training to follow the protocol consistently. Functional testing had no benefits over anatomical testing with CTCA, which may allow cost savings in some departments.

Spontaneous coronary artery dissection as a cause of sudden cardiac death in the peripartum period.

Spontaneous coronary artery dissection is a rare cause of acute coronary syndromes and can be potentially fatal. The authors describe a case of multi-vessel coronary artery dissection occurring in a young postpartum mother. The diagnosis was established by coronary artery angiography. However, the patient died following a cardiac arrest. The authors discuss the methods of investigation available and the different treatment options.
