Background—Accurate models to predict mortality are needed for risk stratification in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods and Results—We examined 5745 patients with STEMI undergoing primary PCI in the Assessment of Pexelizumab in Acute Myocardial Infarction Trial within 6 hours of symptom onset. A Cox proportional hazards model incorporating regression splines to accommodate nonlinearity in the log hazard ratio (HR) scale was used to determine baseline independent predictors of 90-day mortality. At 90 days, 271 (4.7%) of 5745 patients died. Independent correlates of 90-day mortality were (in descending order of statistical significance) age (HR, 2.03/10-y increments; 95% CI, 1.80 to 2.29), systolic blood pressure (HR, 0.86/10-mm Hg increments; 95% CI, 0.82 to 0.90), Killip class (class 3 or 4 versus 1 or 2) (HR, 4.24; 95% CI, 2.97 to 6.08), heart rate (>70 beats per minute) (HR, 1.45/10-beat increments; 95% CI, 1.31 to 1.59), creatinine (HR, 1.23/10-&mgr;mol/L increments >90 &mgr;mol/L; 95% CI, 1.13 to 1.34), sum of ST-segment deviations (HR, 1.25/10-mm increments; 95% CI, 1.11 to 1.40), and anterior STEMI location (HR, 1.47; 95% CI, 1.12 to 1.93) (c-index, 0.82). Internal validation with bootstrapping confirmed minimal overoptimism (c-index, 0.81). Conclusions—Our study provides a practical method to assess intermediate-term prognosis of patients with STEMI undergoing primary PCI, using baseline clinical and ECG variables. This model identifies key factors affecting prognosis and enables quantitative risk stratification that may be helpful in guiding clinical care and for risk adjustment for observational analyses.

Sind neue diagnostische Verfahren hilfreich

Holger Nef; Helge Möllmann; Albrecht Elsässer; Christian W. Hamm

ZusammenfassungNeue diagnostische Verfahren wie die Druckdrahtmessung (FFR) und optische Kohärenztomografie (OCT) wurden bisher trotz ausreichender Datenlage nur wenig eingesetzt. Seit dem Jahreswechsel besteht nun die Möglichkeit einer Vergütung. Somit erscheint zukünftig eine Entscheidung hinsichtlich der Therapie einer koronaren Herzerkrankung bei vorliegender Stenose nicht nur aufgrund einer visuellen Abschätzung möglich, sondern auch auf der Grundlage einer objektiven Messung der hämodynamischen Relevanz. Eine kürzlich vorgestellte Studie konnte belegen, dass eine aufgrund der erhobenen FFR neu festgelegten Therapie gegenüber einer ursprünglich auf rein angiografischen Gesichtspunkten basierenden Therapieentscheidung sicher und für den Patienten prognostisch günstig ist.
