Patient outcomes following percutaneous coronary intervention (PCI) are predominantly determined by two factors: clinical presentation and comorbidities. For example, a patient presenting in cardiogenic shock has a predicted in-hospital mortality in excess of 50%, whereas the corresponding figure for uncomplicated non-ST elevation myocardial infarction (NSTEMI) is less than 1%. A third important factor is the quality of care provided to the patient. Quantification of the relative contribution of these three components to short- and long-term mortality and morbidity is required for several reasons: it informs both the patient and physician in deciding upon the optimal management strategy; it underpins appropriately informed consent; and, by recognizing modifiable elements in the treatment process, it can be used to drive improvements in healthcare delivery.
