Risk Stratification for Patients in Cardiogenic Shock After Acute Myocardial Infarction

BACKGROUND Mortality in cardiogenic shock (CS) remains high. Early risk stratification is crucial to make adequate treatment decisions. OBJECTIVES This study sought to develop an easy-to-use, readily available risk prediction score for short-term mortality in patients with CS, derived from the IABP-SHOCK II (Intraaortic Balloon Pump in Cardiogenic Shock) trial. METHODS The score was developed using a stepwise multivariable regression analysis. RESULTS Six variables emerged as independent predictors for 30-day mortality and were used as score parameters: age > 73 years, prior stroke, glucose at admission >10.6 mmol/l (191 mg/dl), creatinine at admission >132.6 mmol/l (1.5 mg/dl), Thrombolysis In Myocardial Infarction flow grade 5 mmol/l. Either 1 or 2 points were attributed to each variable, leading to a score in 3 risk categories: low (0 to 2), intermediate (3 or 4), and high (5 to 9). The observed 30-day mortality rates were 23.8%, 49.2%, and 76.6%, respectively (p <0.0001). Validation in the IABP-SHOCK II registry population showed good discrimination with an area under the curve of 0.79. External validation in the CardShock trial population (n = 137) showed short-term mortality rates of 28.0% (score 0 to 2), 42.9% (score 3 to 4), and 77.3% (score 5 to 9; p <0.001) and an area under the curve of 0.73. Kaplan-Meier analysis revealed a stepwise increase in mortality between the different score categories (0 to 2 vs. 3 to 4: p = 0.04; 0 to 2 vs. 5 to 9: p = 0.008). CONCLUSIONS The IABP-SHOCK II risk score can be easily calculated in daily clinical practice and strongly correlated with mortality in patients with infarct-related CS. It may help stratify patient risk for short-term mortality and might, thus, facilitate clinical decision making.

Prognostic Impact of Active Mechanical Circulatory Support in Cardiogenic Shock Complicating Acute Myocardial Infarction, Results from the Culprit-Shock Trial

Objectives: To analyze the use and prognostic impact of active mechanical circulatory support (MCS) devices in a large prospective contemporary cohort of patients with cardiogenic shock (CS) complicating acute myocardial infarction (AMI). Background: Although increasingly used in clinical practice, data on the efficacy and safety of active MCS devices in patients with CS complicating AMI are limited. Methods: This is a predefined subanalysis of the CULPRIT-SHOCK randomized trial and prospective registry. Patients with CS, AMI and multivessel coronary artery disease were categorized in two groups: (1) use of at least one active MCS device vs. (2) no active MCS or use of intra-aortic balloon pump (IABP) only. The primary endpoint was a composite of all-cause death or renal replacement therapy at 30 days. Results: Two hundred of 1055 (19%) patients received at least one active MCS device (n = 112 Impella®; n = 95 extracorporeal membrane oxygenation (ECMO); n = 6 other devices). The primary endpoint occurred significantly more often in patients treated with active MCS devices compared with those without active MCS devices (142 of 197, 72% vs. 374 of 827, 45%; p < 0.001). All-cause mortality and bleeding rates were significantly higher in the active MCS group (all p < 0.001). After multivariable adjustment, the use of active MCS was significantly associated with the primary endpoint (odds ratio (OR) 4.0, 95% confidence interval (CI) 2.7–5.9; p < 0.001). Conclusions: In the CULPRIT-SHOCK trial, active MCS devices were used in approximately one fifth of patients. Patients treated with active MCS devices showed worse outcome at 30 days and 1 year

Individualised treatment targets in patients with type-2 diabetes and hypertension

Abstract Aim Patients with type-2 diabetes mellitus (T2DM) are at high risk of cardiovascular events, accentuated in the presence of hypertension. At present, it is unclear to what extent the guidelines for the management of T2DM, advocating reduction in HbA1c levels to below target levels, are being adhered to in clinical practice. Methods DIALOGUE was a prospective, observational, non‐interventional registry performed across multiple centres in Germany. Patients aged 18 years or older who had T2DM and hypertension for whom the treating physician considered blood glucose lowering medication as inadequate and/or not safe/tolerable and chose to add a further oral drug or switch drug treatment were included. Patients were assigned a treatment target HbA1c value (≤ 6.5% [strict]; > 6.5 to ≤ 7.0% [intermediate]; > 7.0 to ≤ 7.5% [lenient]). Results 8568 patients with T2DM and hypertension were enrolled. 6691 (78.1%) had 12-month follow-up. Patients who were assigned a strict HbA1c treatment target (n = 2644) were younger, had shorter diabetes duration, and less comorbidity in comparison to those with intermediate (n = 2912) or lenient targets (n = 1135). Only 53.1% of patients achieved their HbA1c treatment target (46.2% [strict], 56.8% [intermediate], 59.4% [lenient]). There was little sign of treatment intensification for patients that had not achieved their HbA1c target. Conclusions Achievement of treatment targets was poor, leaving many patients with sub-optimal blood glucose levels. The apparent reluctance of physicians to intensify antidiabetic drug therapy is alarming, especially considering the evidence pointing to an association of hyperglycaemia and microvascular complications in patients with T2DM

Impact of cardiac comorbidities on early and 1-year outcome after percutaneous mitral valve interventions: data from the German transcatheter mitral valve interventions (TRAMI) registry

The use of the MitraClip system has gained widespread acceptance for the treatment of patients with mitral regurgitation (MR) who are not suitable for the conventional surgery. This study sought to investigate the early and 1-year outcome after MitraClip therapy of patients with MR and cardiac comorbidities. Outcomes through 12-month follow-up of patients (n = 528) who underwent MitraClip implantation were obtained from the German transcatheter mitral valve interventions (TRAMI) registry. The majority of these patients (n = 409, 77.5 %) also suffered from coronary artery disease (CAD). Patients with a dilated cardiomyopathy (DCM, n = 65, 12.3 %) or concomitant valvular aortic disease (AV, n = 54, 10.2 %) were less frequent. Although the prevalent pathogenesis was functional MR, patients with DCM had significantly more frequent a functional MR (96.9 %) compared to patients with CAD (74.9 %) or AV (62.5 %, p < 0.001). Technical success was achieved in 97.5 % of patients. Procedural echocardiograms demonstrated in the vast majority of patients a reduction from severe MR III to mild MR I with no difference between the groups (p = 0.83). The peri-procedural complication rate was very low. At 30-day and 12-month follow-up, the majority of patients were in NYHA functional class II or lower. The rate of death, stroke, and myocardial infarction (MACCE) was comparable in the three patient groups during 12-month follow-up (DCM 26.9 %, CAD 30.3 % and AV 27.5 %, p = 0.85). The MitraClip implantation is feasible and safe even in high-risk patients with MR and cardiac comorbidities

Percutaneous Mitral Valve Repair With the MitraClip System According to the Predicted Risk by the Logistic EuroSCORE: Preliminary Results From the German Transcatheter Mitral Valve Interventions (TRAMI) Registry

Objective: To evaluate in-hospital and short-term outcomes of percutaneous mitral valve repair according to patients' logistic EuroSCORE (logEuroSCORE) in a multicenter registry Background: The logEuroSCORE is an established tool to predict the risk of mortality during cardiac surgery. In high-risk patients percutaneous mitral valve repair with the MitraClip system represents a less-invasive alternative Methods: Data from 1002 patients, who underwent percutaneous mitral valve repair with the MitraClip system, were analyzed in the German Transcatheter Mitral Valve Interventions (TRAMI) Registry. A logEuroSCORE (mortality risk in %) >= 20 was considered high risk Results: Of all patients, 557 (55.6%) had a logEuroSCORE >= 20. Implantation of the MitraClip was successful in 95.5 % (942/986) patients. Moderate residual mitral valve regurgitation was more often detected in patients with a logEuroSCORE >= 20 (23.8% vs. 17.1%, respectively, P = 20 the procedural complication rate was 8.9% (vs. 6.4, n.s.) and the in-hospital MACCE rate 4.9% (vs. 1.4% P = 20 and logEuroSCORE = 20 with similar procedural results compared to patients with lower predicted risk. Although mortality was four times higher than in patients with logEuroSCORE = 20, moderate residual mitral valve regurgitation was more frequent. (C) 2014 Wiley Periodicals, Inc

Effects of ON-Hours Versus OFF-Hours Admission on Outcome in Patients With Myocardial Infarction and Cardiogenic Shock

Background: The management of patients with acute myocardial infarction complicated by cardiogenic shock is highly complex, and outcomes may depend on the time of hospital admission and subsequent intervention (ie, ON-hours versus OFF-hours). The CULPRIT-SHOCK trial (Culprit Lesion Only PCI Versus Multivessel PCI in Cardiogenic Shock) demonstrated superior outcome for culprit-lesion-only versus immediate multivessel percutaneous coronary intervention in patients presenting with acute myocardial infarction, multivessel disease, and cardiogenic shock. However, it is unknown whether the time of hospital admission affects the overall outcome of these high-risk patients. Methods: We analyzed patients from the CULPRIT-SHOCK trial with respect to the time of hospital admission. We divided patients in ON-hours and OFF-hours groups and further stratified them according to their individual revascularization strategy. Outcome measures consisted of a composite end point of death or renal-replacement therapy within 30 days and mortality within 1 year. Results: Out of 686 patients randomized in the CULPRIT-SHOCK trial, 444 patients (64.7%) presented during ON-hours, whereas 242 patients (35.3%) presented during OFF-hours. Death or renal-replacement therapy at 30 days occurred to a similar extent in patients admitted during ON-hours (51.0%) and OFF-hours (50.0%;P=0.80). Similarly, 1-year mortality was not affected by the time of hospital admission (54.4% ON-hours versus 51.7% OFF-hours,P=0.49). Regardless of admission time, patients had a benefit from culprit-lesion-only as compared to immediate multivessel percutaneous coronary intervention. The composite end point at 30 days occurred in 45.1% versus 57.6% of patients admitted ON-hours and in 47.7% versus 51.9% of patients admitted OFF-hours (P-interaction=0.29). Death within 1 year occurred in 49.4% versus 60.0% of patients admitted during ON-hours and in 51.4% versus 51.9% of patients admitted OFF-hours (P-interaction=0.20). Conclusions: Among patients with myocardial infarction and cardiogenic shock, the risk of death or renal-replacement therapy at 30 days, and mortality at 1 year did not differ significantly according to the time of hospital admission.
