Heart Failure and Cardiorenal Syndrome: A Narrative Review on Pathophysiology, Diagnostic and Therapeutic Regimens-From a Cardiologist's View.

In cardiorenal syndrome (CRS), heart failure and renal failure are pathophysiologically closely intertwined by the reciprocal relationship between cardiac and renal injury. Type 1 CRS is most common and associated with acute heart failure. A preexistent chronic kidney disease (CKD) is common and contributes to acute kidney injury (AKI) in CRS type 1 patients (acute cardiorenal syndrome). The remaining CRS types are found in patients with chronic heart failure (type 2), acute and chronic kidney diseases (types 3 and 4), and systemic diseases that affect both the heart and the kidney (type 5). Establishing the diagnosis of CRS requires various tools based on the type of CRS, including non-invasive imaging modalities such as TTE, CT, and MRI, adjuvant volume measurement techniques, invasive hemodynamic monitoring, and biomarkers. Albuminuria and Cystatin C (CysC) are biomarkers of glomerular filtration and integrity in CRS and have a prognostic impact. Comprehensive "all-in-one" magnetic resonance imaging (MRI) approaches, including cardiac magnetic resonance imaging (CMR) combined with functional MRI of the kidneys and with brain MRI are proposed for CRS. Hospitalizations due to CRS and mortality are high. Timely diagnosis and initiation of effective adequate therapy, as well as multidisciplinary care, are pertinent for the improvement of quality of life and survival. In addition to the standard pharmacological heart failure medication, including SGLT2 inhibitors (SGLT2i), renal aspects must be strongly considered in the context of CRS, including control of the volume overload (diuretics) with special caution on diuretic resistance. Devices involved in the improvement of myocardial function (e.g., cardiac resynchronization treatment in left bundle branch block, mechanical circulatory support in advanced heart failure) have also shown beneficial effects on renal function.

Association of autosomal dominant polycystic kidney disease, asymptomatic multiple giant coronary arteries aneurysms and abdominal aortic aneurysm: a case report.

Autosomal dominant polycystic kidney disease (ADPKD) is a systemic disease characterized by the formation of multiple cysts in several organs. The formation of aneurysms accompanying this disease is being increasingly reported in the literature, and mutations in PKD-1 and PKD-2 are suspected in this etiology. Although the association between ADPKD and multiple coronary arteries aneurysms (CAA) was reported several times, we are presenting a case with the combination of ADPKD, multiple giant CAAs, abdominal aortic aneurysms and a suspected intracranial aneurysm, which has never been reported. The asymptomatic presentation of these multiple aneurysms might support the recommendations for further diagnostic investigations in these patients.

A Rare Case of an Advanced Gastric Adenocarcinoma in a Teenage Syrian Boy.

In this report, we describe a case of a gastric cancer in young age group with delayed diagnosis and poor prognosis. We report a rare case of a 16-year-old teenager with an advanced moderately differentiated gastric adenocarcinoma without any relevant history. He presented mainly with dysphagia, postprandial vomiting, and eventually hematemesis. On exploratory laparotomy, the tumor was in advanced stage, the excision was not performed, multiple biopsies and a feeding jejunostomy were done, and the patient was referred to receive a palliative therapy. Reporting such cases introduces a better understanding of the relation between gastric cancer and young ages.
