- Previous studies have established a relationship between socioeconomic status (SES) and survival in coronary heart disease. Acute cardiac care in Sweden is considered to be excellent and independent of SES. We studied the influence of area-level socioeconomic status on mortality after hospitalization for acute myocardial infarction (AMI) between 1995 and 2013 in the Gothenburg metropolitan area, which has little over 800,000 inhabitants and includes three city hospitals.

- Background: Myocardial ischemia is associated with alterations in cardiac metabolism, resulting in decreased fatty acid oxidation and increased lipid accumulation. Here we investigate how myocardial lipid content and dynamics affect the function of the ischemic heart, and focus on the role of the lipid droplet protein perilipin 5 (Plin5) in the pathophysiology of myocardial ischemia. Methods and results: We generated Plin5(-/-) mice and found that Plin5 deficiency dramatically reduced the triglyceride content in the heart. Under normal conditions, Plin5(-/-) mice maintained a close to normal heart function by decreasing fatty acid uptake and increasing glucose uptake, thus preserving the energy balance. However, during stress or myocardial ischemia, Plin5 deficiency resulted in myocardial reduced substrate availability, severely reduced heart function and increased mortality. Importantly, analysis of a human cohort with suspected coronary artery disease showed that a common noncoding polymorphism, rs884164, decreases the cardiac expression of PLIN5 and is associated with reduced heart function following myocardial ischemia, indicating a role for Plin5 in cardiac dysfunction. Conclusion: Our findings indicate that Plin5 deficiency alters cardiac lipid metabolism and associates with reduced survival following myocardial ischemia, suggesting that Plin5 plays a beneficial role in the heart following ischemia.

- Takotsubo syndrome (TS) is a life-threatening acute heart failure syndrome. However, little is known about risk factors for worse outcomes in TS and no high-risk ECG criteria have been defined. We sought to identify ECG predictors of life-threatening in-hospital complications in TS.Using the nationwide Swedish Angiography and Angioplasty Registry (SCAAR) we obtained data on all consecutive patients undergoing coronary angiography at Sahlgrenska University Hospital between June 2008 and February 2019. For all patients with TS we conducted in-depth chart reviews to confirm the TS diagnosis. For those with confirmed TS we then evaluated all ECGs obtained during the index hospitalization. The primary endpoint was the occurrence of in-hospital major adverse cardiac event (MACE), defined as the composite of death, ventricular tachycardia or fibrillation (VT/VF), or atrioventricular block ≥2 or asystole ≫10s. We identified 215 patients with TS (mean age 69±13years; 93% women). MACE occurred in 34 patients (16%), of whom 20 had VT/VF (9,3%). Patients with MACE were less likely than those without MACE to have sinus rhythm (85% versus 96%, p=0.025) or T-wave inversion (29% versus 51%, p=0.025). After propensity score adjustment T-wave inversion was independently associated with lower MACE risk (adjusted odds ratio [AdjOR] 0.28, 95% confidence interval [CI] 0.10-0.76, p=0.012) and VT/VF (AdjOR 0.24, 95% CI 0.06-0.94, p=0.041).T-wave inversion is common in TS and is associated with lower risk of MACE, driven by a lower risk of VT/VF.

- Stress-induced cardiomyopathy (SIC) is a common syndrome with substantial morbidity and mortality. SIC is common in intensive care units' patients. No therapeutic intervention for SIC has been evaluated in randomized clinical trial so far. Our aim was to investigate whether isoflurane is cardioprotective in an experimental SIC model.
