Post Heart Attack DNA Methylation: A Pilot Study
Myocardial infarction (MI) induces systemic biological changes, some of which may be reflected in DNA methylation patterns. This study investigates whether MI survivors retain distinct epigenetic signatures detectable in saliva DNA, a convenient and non-invasive biological sample. In a retrospective case-control design, genome-wide DNA methylation was assessed using the Illumina EPIC 850K array in saliva samples from 329 MI survivors and 1,438 age-matched healthy controls. After stringent quality control and removal of sex chromosome probes, methylation β-values at autosomal CpG sites were compared using the Mann–Whitney U test. Differentially methylated positions (DMPs) were defined using a significance threshold of p < 2×10⁻⁴ (FDR q < 0.05). Forty CpG sites showed significant methylation differences between MI survivors and controls. The majority (34/40) were hypermethylated in the MI group. Notable DMPs included loci in SELP, IRX5, AVPR1A, KCNH2, and CHGA, suggesting involvement of inflammatory, cardiac conduction, and neurohormonal pathways. Several genes had multiple significant CpGs, reinforcing their potential relevance. The largest effect was observed at ICAM5 (β ~3.9%). This study identifies a reproducible set of differentially methylated loci in saliva DNA of MI survivors, persisting up to three years post-event. These epigenetic changes may reflect both lasting physiological responses to MI and potential pre-existing risk markers. The findings support saliva-based methylation profiling as a viable tool for exploring cardiovascular epigenetics and highlight novel candidate genes for further investigation.

Management of Fluid Overload in Acute Settings
This entry provides a comprehensive review of fluid overload management, specifically targeting therapeutic strategies for patients with diuretic resistance or refractory volume overload. It covers the pathophysiology of edema formation and the challenges associated with fluid removal in patients with chronic conditions such as congestive heart failure, cirrhosis, and chronic kidney disease. Key treatments discussed include combination therapy with loop and thiazide diuretics, use of alternative loop diuretics with higher bioavailability, and the comparative effectiveness of bolus versus continuous drip loop diuretics. For patients unresponsive to pharmacologic management, the entry also examines mechanical ultrafiltration methods, comparing hemodialysis (HD), continuous venovenous hemofiltration (CVVH), and specialized CHF solutions (Aquamid). The entry emphasizes evidence-based approaches, highlighting studies that support optimized fluid management to improve patient outcomes and reduce hospital readmissions.

The Disease of Sympathetic Overdrive (DSO)
The sympathetic nervous system (SNS) is one of components of the autonomic system (ANS), whose overall ultimate function is to prepare the body for activities, which is a systemic response that affects many organs and systems. Accumulating evidence suggests that the SNS plays a crucial role in human numerous diseases. In the present article, we review the SNS dysfunction and even the disease of sympathetic overdrive (DSO) impact on cardiovascular, digestive, endocrine and metabolic as well as mental nervous system and various systems of the body. Despite the fact that the existence of this disease has not been truly recognized and confirmed. Here we proposed a hypothesis of the disease as DSO for the first time. The aim of the study is identifying the framework of the DSO, including the risk-factors, symptoms, end-points, mechanisms, and the strategies of management in order to improve both of the theory and clinical practice.As the hypothesis of DSO is novel born , the enrichment and improvement of hypothesis of the DSO are surely needed.

Postoperative Myocardial Infarction after Non-Cardiac Surgery
In patients undergoing major non-cardiac surgery, perioperative myocardial infarction (PMI) is a threatened complication. Every year, not less than 300 million non-cardiac surgery interventions are performed in the world. Perioperative mortality after non-cardiac surgery is estimated at 2% in patients over 45 years of age. Cardiovascular events account for half of these deaths, and most are due to perioperative myocardial infarction (MINS). The diagnosis of postoperative myocardial infarction, before the introduction of cardiac biomarkers, was based on symptoms and electrocardiographic changes and its incidence was largely underestimated. The incidence of MINS when a standard troponin assay is used ranges between 8 and 19% but increases to 20–30% with high-sensitivity troponin assays. Higher troponin values suggesting myocardial injury, both with or without a definite diagnosis of myocardial infarction, are associated with an increase in 30-day and 1-year mortality.

Dietary Salt Restriction and MDP for Cardiometabolic Health
The dietary restriction of salt intake and the adhesion to Mediterranean dietary pattern (MDP) are among the most recommended lifestyle modifications for the prevention of cardiovascular diseases. A large amount of evidence supports these recommendations. Likewise, findings from observational and clinical studies suggest a causal role of excess salt intake in blood pressure increase, cardiovascular organ damage, and the incidence of cardiovascular diseases. In this context, it is also conceivable that the beneficial effects of these two dietary patterns overlap because Mediterranean dietary patterns are typically characterized by a large consumption of plant-based foods with low sodium content. However, there is little data on this issue, and heterogeneous results are available on the relationship between adherence to salt restriction and to Mediterranean dietary patterns.

Mechanical Circulatory Support Systems in Fulminant Myocarditis
Fulminant myocarditis (FM) constitutes a severe and life-threatening form of acute cardiac injury associated with cardiogenic shock. The condition is characterised by rapidly progressing myocardial inflammation, leading to significant impairment of cardiac function. Due to the acute and severe nature of the disease, affected patients require urgent medical attention to mitigate adverse outcomes. Besides symptom-oriented treatment in specialised intensive care units (ICUs), the necessity for temporary mechanical cardiac support (MCS) may arise. Numerous patients depend on these treatment methods as a bridge to recovery or heart transplantation, while, in certain situations, permanent MCS systems can also be utilised as a long-term treatment option.

The Efficacy of Spirulina Supplementation on Diabetes
As a result of rising mortality rates due to cardiovascular diseases (CVDs), there has been a growing urgency to find alternative approaches to conventional pharmaceutical treatment to prevent the onset of chronic diseases. Arthrospira platensis, commonly known as Spirulina, is a blue-green cyanobacterium, classified as a “superfood”, used worldwide as a nutraceutical food supplement due to its remarkable nutritional value, lack of toxicity, and therapeutic effects. Many research studies have demonstrated that Spirulina has therapeutic functions such as antioxidant, anti-inflammatory, hypolipidemic, antidiabetic, and brain-protective properties.

Wearable Technology for Monitoring Electrocardiograms in Adults
In the rapidly evolving landscape of continuous electrocardiogram (ECG) monitoring systems, there is a heightened demand for non-invasive sensors capable of measuring ECGs and detecting heart rate variability (HRV) in diverse populations, ranging from cardiovascular patients to sports enthusiasts. Challenges like device accuracy, patient privacy, signal noise, and long-term safety impede the use of wearable devices in clinical practice.
