Many cardiopulmonary complications occur after aneurysmal subarachnoid hemorrhage. This is due to sympathetic nervous system activation which results in release of norepinephrine from myocardial sympathetic nerves. Cardiac troponin I is a marker for diagnosis of cardiac injury. Elevated levels of troponin in these patients are associated with worse clinical outcomes. PubMed was searched for literature using regular and Medical Subject Heading (MeSH) keywords for data collection. Papers published in English language involving human subjects within the last 20 years focusing on cardiac troponin elevation following subarachnoid hemorrhage were included. Systemic complications that occur after subarachnoid hemorrhage worsen the clinical outcome of patients and have negative effects on the mortality and morbidity of these patients. Cardiac troponin I elevation is significantly associated with the severity of the stroke, poor neurological status, longer ICU stay, and death. Cardiac troponin I should be measured in patients presented with acute stroke. Hemodynamic monitoring and appropriate supportive care can improve clinical outcomes.

Impaired Exercise Capacity in High-Risk Diabetic Cardiomyopathy: The ARISE-HF Cardiopulmonary Exercise Testing Subanalysis.
Circ Heart Fail
January 2025
Cardiology Division, Massachusetts General Hospital, Harvard Medical School, Boston (Y.L., J.L.J., G.D.L.).
Background: Objective indices of functional capacity in patients with diabetic cardiomyopathy and stage B heart failure (HF) have not been comprehensively defined. We sought to characterize the cardiopulmonary exercise characteristics of individuals with diabetic cardiomyopathy at high risk for overt HF.
Methods: The relationships from cardiopulmonary exercise testing with clinical and laboratory characteristics of participants with diabetic cardiomyopathy were evaluated using baseline data from the ARISE-HF trial (Aldose Reductase Inhibition for Stabilization of Exercise Capacity in Heart Failure).
Peripartum Cardiomyopathy and Takotsubo Cardiomyopathy: Rare Contributors to Cardiac Causes of Maternal Mortality.

Neurology, Mercy Hospital Springfield, Springfield, USA.
Peripartum cardiomyopathy (PPCM) and takotsubo cardiomyopathy (TCM) are cardiac conditions that can occur in the peripartum period. They have distinct characteristics and incidence rates; although rare, both contribute to the second leading cause of all-cause maternal mortality in the state of Missouri. PPCM can lead to heart failure, and TCM can cause acute arrhythmias leading to sudden cardiac death in otherwise healthy individuals.

Background: Impaired renal function can increase cardiac troponin levels due to reduced elimination, potentially affecting its diagnostic utility. Limited data exist on high-sensitivity cardiac troponin I (hs-cTnI) kinetics after cardiac surgery relative to renal function. This study evaluates how impaired renal function influences hs-cTnI kinetics following cardiac surgery, distinguishing between patients with and without postoperative myocardial infarction (PMI).

Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory vascular disease of medium-sized arteries that causes abnormal cellular growth in arterial walls and most commonly affects young to middle-aged women (20-50 years of age). While FMD often involves the renal arteries, it can affect any arterial bed. FMD has a characteristic angiographic appearance of a "string of beads.

Intensive care unit-acquired weakness (ICU-AW) is recognized as newly-acquired bilateral muscle weakness, which is a complication of critical illness in the ICU; however, there are no reports on the pathogenesis and early predictors of ICU-AW specifically associated with cardiogenic shock (CS). Therefore, this study aimed to investigate the clinical characteristics of ICU-AW in patients with CS requiring mechanical circulatory support (MCS). This study was a single-center, prospective, and observational study.
