- Background: In traditional literature, it appears that "anteroseptal" MIs with Q waves in V1-V3 involve basal anteroseptal segments although studies have questioned this belief. Methods: We studied patients with first acute anterior Q-wave (>. 30. ms) MI. All underwent late gadolinium enhancement (LGE) cardiac magnetic resonance imaging (MRI). Results: Those with Q waves in V1-V2 (n = 7) evidenced LGE >. 50% in 0%, 43%, 43%, 57%, and 29% of the basal anteroseptal, mid anteroseptal, apical anterior, apical septal segments, and apex, respectively. Patients with Q waves in V1-V3 (n = 14), evidenced involvement was 14%, 43%, 43%, 50%, and 7% of the same respective segments. In those with extensive anterior Q waves (n = 7), involvement was 0%, 71%, 57%, 86%, and 86%. Conclusions: Q-wave MI in V1-V2/V3 primarily involves mid- and apical anterior and anteroseptal segments rather than basal segments. Data do not support existence of isolated basal anteroseptal or septal infarction. "Anteroapical infarction" is a more appropriate term than "anteroseptal infarction.".

- Background: Anteroseptal ST elevation myocardial infarction (STEMI) is traditionally defined on the electrocardiogram (ECG) by ST elevation (STE) in leads V1-V3, with or without involvement of lead V4. It is commonly taught that such infarcts affect the basal anteroseptal myocardial segment. While there are suggestions in the literature that Q waves limited to V1-V4 represent predominantly apical infarction, none have evaluated anteroseptal ST elevation territories. We compared the distribution of the myocardium at risk (MaR) in STEMI patients presenting with STE limited to V1-V4 and those with more extensive STE (V1-V6). Methods: We identified patients in the MITOCARE study presenting with a first acute STEMI and new STE in at least two contiguous anterior leads from V1 to V6. Patients underwent cardiac magnetic resonance (CMR) imaging three to five days after acute infarction. Results: Thirty-two patients met inclusion criteria. In patients with STE in V1-V4 (n = 20), myocardium at risk (MaR) > 50% was seen in 0%, 85%, 75%, 100%, and 90% in the basal anteroseptal, mid anteroseptal, apical anterior, apical septal segments, and apex, respectively. The group with STE in V1-V6 (n = 12), MaR > 50% was seen in 8%, 83%, 83%, 92%, and 83% of the same segments. Conclusions: Patients with acute STEMI and STE in leads V1-V4, exhibit MaR in predominantly apical territories and rarely in the basal anteroseptum. We found no evidence to support existence of isolated basal anteroseptal or septal STEMI. “Anteroapical” infarction is a more precise description than “anteroseptal” infarction for acute STEMI patients exhibiting STE in V1-V4.

- Aims: Peripheral artery disease (PAD) constitute a high-risk with adverse clinical outcomes. We aimed to investigate the cardiovascular outcomes following myocardial infarction (MI). Methods and results: This nationwide, Danish register-based follow-up study includes all patients experiencing an MI between 2000 and 2017. Patients with and without PAD were compared. Multivariable logistic regression was used to derive relative risks of 1-year major adverse cardiovascular events (MACE; all-cause mortality, reinfarction, stroke or heart failure). Individual components, cardiovascular mortality, and bleeding, standardized to age, sex and comorbidity distributions of all patients were assessed. MI patients with PAD (n = 5083, 2.9%) were older and more comorbid compared to patients without PAD (n = 174,673). After standardization, PAD was associated with higher 1-year relative risks of MACE (RR 1.21 [95% CI 1.17;1.25]), all-cause (RR 1.29 [95% CI 1.24;1.35]) and cardiovascular mortality (RR 1.3 [95% CI 1.24;1.36]), reinfarction (RR 1.17 [95% CI 1.11;1.22]), stroke (RR 1.12 [95% CI 0.92;1.32]), heart failure (RR 1.22 [95% CI 1.12;1.32]), and bleeding episodes (RR 1.25 [95% CI 1.04,1.46]). Similar results were seen in 30-day survivors after adjustment for antithrombotic post-discharge medication for MACE (RR 1.25 [95% CI 1.20,1.31]), all-cause mortality (RR 1.47 [95% CI 1.37,1.57], cardiovascular mortality (RR 1.49 [95% CI 1.37,1.61]), reinfarction (RR 1.17 [95% CI 1.08,1.12]) and heart failure (RR 1.22 [95% CI 1.12,1.32]). Conclusion: Comparing to patients without PAD, patients with PAD had increased 1-year relative risk of MACE, all-cause mortality, reinfarction, stroke, heart failure, cardiovascular mortality and bleeding following MI. The low prevalence of PAD is suggestive of considerable under-diagnosing.

- Treatment of acute ST-elevation myocardial infarction (STEMI) by reperfusion using percutaneous coronary intervention (PCI) or thrombolysis has provided clinical benefits; however, it also induces considerable cell death. This process is called reperfusion injury. The continuing high rates of mortality and heart failure after acute myocardial infarction (AMI) emphasize the need for improved strategies to limit reperfusion injury and improve clinical outcomes. The objective of this study is to assess safety and efficacy of TRO40303 in limiting reperfusion injury in patients treated for STEMI. TRO40303 targets the mitochondrial permeability transition pore, a promising target for the prevention of reperfusion injury. This multicenter, double-blind study will randomize patients with STEMI to TRO40303 or placebo administered just before balloon inflation or thromboaspiration during PCI. The primary outcome measure will be reduction in infarct size (assessed as plasma creatine kinase and troponin I area under the curve over 3 days). The main secondary endpoint will be infarct size normalized to the myocardium at risk (expressed by the myocardial salvage index assessed by cardiac magnetic resonance). The study is being financed under an EU-FP7 grant and conducted under the auspices of the MITOCARE research consortium, which includes experts from clinical and basic research centers, as well as commercial enterprises, throughout Europe. Results from this study will contribute to a better understanding of the complex pathophysiology underlying myocardial injury after STEMI. The present paper describes the rationale, design and the methods of the trial. Copyright (c) 2012 S. Karger AG, Basel

Tidskriftsartikel (refereegranskat)abstract
- Background: Persons with bipolar disorder (BD) have a higher cardiovascular mortality compared to the general population, partially explained by the increased burden of cardiovascular risk factors. Research regarding outcomes following acute coronary syndrome (ACS) in this population remains scarce. Design: This Danish register-based study included patients diagnosed with BD and ACS in the period between January 1st, 1995, to December 31st, 2013. Study participants were matched 1:2 to patients without BD on sex, date of birth, time of ACS diagnosis and comorbidities. The primary outcome of interest was major adverse cardiovascular events (MACE) a composite of all-cause mortality, reinfarction or stroke. MACE and its individual components were compared between patients with and without BD. Results: 796 patients with BD were compared to 1592 patients without BD, both groups had a mean age of first ACS of 66.5 years. MACE was 38% increased (HR 1.38 95% CI 1.25–1.54), all-cause mortality was 71% increased (HR 1.71 95% CI 1.52–1.92), stroke was 94% increased (HR 1.94 95% CI 1.56–2.41) and reinfarction rates were 17% lower (HR 0.83 95% CI 0.69–1.00) in the BD population compared to the population without BD. We also found higher prevalences of heart failure (9.1% vs. 6.5%), valve disease (5.3% vs. 3.5%), anemia (8.7% vs. 5.8%), chronic obstructive pulmonary disease (13.4% vs. 9.3%) and stroke (11.8% vs. 7.8%) in the population with BD at baseline, all p-values <0.05. Conclusion: Bipolar disorder was associated with a higher risk of composite MACE, all-cause mortality, and stroke, after ACS compared to patients without BD.

- Patients with acute coronary syndrome (ACS) are at risk for recurrent adverse events, and multiple reports suggest that this risk is increased in patients with concomitant diabetes mellitus (DM) and peripheral artery disease (PAD). The aim of this article was to investigate cardiovascular outcomes in patients with DM presenting with ACS, stratified by PAD status. Data were derived from 4 randomized post-ACS trials (PLATO [Platelet Inhibition and Patient Outcomes], APPRAISE-2 p Apixaban for Prevention of Acute Ischemic Events 2], TRILOGY [Targeted Platelet Inhibition to Clarify the Optimal Strategy to Medically Manage], and TRACER [Thrombin Receptor Agonist for Clinical Event Reduction in Acute Coronary Syndrome]). Using Cox regression analysis, we investigated major adverse cardiovascular events (MACEs), a composite of cardiovascular mortality, myocardial infarction (MI), or stroke and the individual components of MACE and all-cause mortality in patients with DM, presenting with ACS, stratified by PAD status as the risk modifier. This study included 15,387 patients with a diagnosis of DM and ACS, of whom 1,751 had an additional diagnosis of PAD. PAD was associated with more than doubled rates of MACE (hazard ratio [HR] 2.03, 95% confidence interval [CI] 1.81 to 2.27), all-cause mortality (HR 2.48, 95% CI 2.14 to 2.87), cardiovascular mortality (HR 2.42, 95% CI 2.04 to 2.86), and MI (HR 2.07, 95% CI 1.79 to 2.38). Patients with both PAD and DM were also more optimally treated with antihypertensive, antidiabetic, and statin medication at baseline. In conclusion, this analysis of 4 major post-ACS trials showed that patients with DM and PAD had a substantially higher risk of MACE, cardiovascular mortality, all-cause mortality, and MI despite being optimally treated with guideline-based therapies.

- AIMS: We aimed to investigate major adverse cardiac events (MACE: defined as all-cause mortality, re-infarction, and stroke), length of hospital stays (LOS), and comorbidities following acute coronary syndrome (ACS) in a population with schizophrenia.METHODS AND RESULTS: This Danish register study included patients diagnosed with ACS in the period between 1995 and 2013 with a preceding diagnosis of schizophrenia (n = 726). Each patient was matched to a psychiatric healthy control 1:2 on sex, age, year of ACS diagnosis, and number of comorbidities (total n = 2178). After performing Cox regression and Kaplan-Meier analyses, we found that patients with schizophrenia had an increased risk of MACE [hazard ratio (HR) 1.62, 95% confidence interval (CI) 1.45-1.81], all-cause mortality (HR 2.54, 95% CI 2.22-2.90), and stroke (HR 1.51, 95% CI 1.15-1.99). No differences were found in the re-infarction rates and LOS between the populations. Patients with schizophrenia had higher prevalence's diabetes, anaemia, heart failure, cardiomyopathy, chronic obstructive lung disease, and stroke. Nonetheless, we found lower prevalence's of hypertension and hyperlipidaemia.CONCLUSION: Schizophrenia is associated with an increased risk of MACE despite a lower prevalence of some diagnosed traditional cardiac risk factors which may indicate underdiagnosing of these. Awareness of treatment bias may improve this increased risk.

- AIM: Schizophrenia is associated with high cardiovascular mortality predominantly as a result of acute coronary syndrome (ACS). The aim of this study is to analyze time trends of coronary procedures, guideline-based therapy, and all-cause mortality in patients diagnosed with schizophrenia.METHODS AND RESULTS: This Danish nationwide register-based study analyzed 734 patients with a baseline diagnosis of schizophrenia and an incident diagnosis of ACS in the period between January 1, 1996, and December 31, 2015. The 734 patients with schizophrenia were matched to 2,202 psychiatric healthy controls (PHC). No change over time was seen in the relative difference between the population with schizophrenia and the PHC in the use of coronary angiography, percutaneous coronary intervention, and coronary bypass grafting, nor in 1-year mortality or guideline-based therapy following ACS. Patients with schizophrenia had higher prevalence rates of diabetes, chronic obstructive pulmonary disease, and stroke, and a lower prevalence of hypertension (p < 0.05).CONCLUSION: The gap in the use of coronary procedures, guideline-based therapy, and all-cause mortality following ACS in patients with schizophrenia compared to those without has remained constant over the past 2 decades.
