Diagnosis is a process that identifies, explains, or establishes the individual’s disease from its symptoms and signs. Early and precise diagnosis is crucial since it influences the efficacy of treatment and avoids longterm complications for the infected person. Further, in the case of infectious diseases, undiagnosed patients can transmit the disease to a healthy population unknowingly. Besides, most of the diseases evolve with the time that significantly affects the clinical outcomes.

Acute myocardial infarction (AMI) with heart failure (HF), is the main cause of increased mortality. Early risk stratification by Killip classification is essential for its management. Today, non-invasive diagnostic methods such as lung ultrasound (LUS) are on the rise due to their ability to provide valuable insights without invasive methods. In this study we aimed to evaluate diagnostic value of LUS in comparison with Killip classes after angiography in AMI patients.

Myocardial infarction (MI) due to coronary artery stenosis compromises vascular endothelial integrity and increases vascular permeability. Concurrently, ensuing myocardial tissue death and necrosis results in the release of danger associated molecular patterns (DAMPs), cytokines, chemokines, bioactive lipids, as well as activation of the complement cascade. 

Multiple myeloma (MM) is a common hematologic malignancy, with 32,110 new cases diagnosed in the United States in 2019, resulting in 12,960 deaths. While neutrophilia
is also a common entity, it most often arises secondary to other etiologies, such as infection or inflammatory processes. 

The COVID-19 virus with severe acute respiratory syndrome (SARS) has a remarkable effect on morbidity and mortality. Non-ST elevation myocardial infarction (NSTEMI) is a category of acute coronary syndrome (ACS) that may represent a primary cardiac manifestation of COVID-19 disease. The QRS-complex fragmentation had been considered a hallmark of structural heart disease. Wavy triple, an electrocardiographic sign (Yasser’s sign) is a new specific diagnostic sign and therapeutic guide for hypocalcemia.
