In this review paper on the pathophysiology of myocardial ischaemia, the recent concepts of the ischaemic cascade, as well as the concepts of stunning and hibernating myocardium, are discussed. It is clear that painful ischaemia is the final phenomenon in the ischaemic cascade and that it is preceded by biochemical disturbances, diastolic and systolic dysfunction and electrocardiographic abnormalities. Silent ischaemia remains a difficult research field.

: Systemic sclerosis (SSc) causes myocardial and microvascular impairment, with subclinical dysfunction and eventually permanent cardio-vascular damage. The long-term influence of SSc therapies on subclinical cardiovascular dysfunction is insufficiently investigated. We aimed to assess 2D and 4D cardiac ultrasound parameters of heart function in patients with different forms of SSc versus controls and to determine the evolution of cardiac function and arterial stiffness parameters under therapy.

: In patients with acute coronary syndrome, electrocardiographic parameters, including ST elevation in lead aVR (aVR-STE), ST depression (aVR-STD), and QTc prolongation, are crucial. This study aims to show the predictive value of a longer QTc in emergency department patients with acute coronary syndrome and ≥1 mm ST elevation or depression in the aVR lead in electrocardiography. : A retrospective analysis was conducted on 1273 patients admitted to the emergency department with a preliminary diagnosis of acute coronary syndrome between 2020 and 2023.

Sodium bicarbonate has been used in the treatment of different pathologies, such as hyperkalemia, cardiac arrest, tricyclic antidepressant toxicity, aspirin toxicity, acute acidosis, lactic acidosis, diabetic ketoacidosis, rhabdomyolysis, and adrenergic receptors' resistance to catecholamine in patients with shock. An ongoing debate about bicarbonate's efficacy and potential harm has been raised for decades because of the lack of evidence supporting its potential efficacy. Despite the guidelines' restrictions, sodium bicarbonate has been overused in clinical practice.

Heart failure (HF) has a multifaceted and complex pathophysiology. Beyond neurohormonal, renin-angiotensin-aldosterone system, and adrenergic hyperactivation, a role for other pathophysiological determinants is emerging. Genetic and epigenetic factors are involved in this syndrome.

Heart failure is characterized by intricate myocardial remodeling that impairs the heart's pumping and/or relaxation capacity, ultimately reducing cardiac output. It represents a major public health burden, given its high prevalence and associated morbidity and mortality rates, which continue to challenge healthcare systems worldwide. Despite advancements in medical science, there are no treatments that address the disease at its core.
