Acute Coronary Syndrome III: Diagnostic Studies

89
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

131
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Acute Coronary Syndrome I: Introduction

284
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Angina II: Classification01:27

Angina II: Classification

108
Angina, also known as angina pectoris, is a chest pain resulting from diminished blood flow to the heart muscle and is often a symptom of coronary artery disease. Angina presents several variants with distinctive attributes, etiologies, and therapeutic approaches. The main types of angina include stable, unstable, variant (Prinzmetal's), microvascular, intractable, and silent ischemia.Stable angina is caused by atherosclerosis, which leads to the formation of plaques that narrow the coronary...

GPCRs Regulate Adenylyl Cylase Activity01:09

GPCRs Regulate Adenylyl Cylase Activity

6.4K
Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of...

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Public Health

Background:

  • Primary angle closure glaucoma (PACG) is a significant cause of visual impairment, particularly in Asia, accounting for 80% of global cases.
  • In India, PACG represents nearly 50% of adult glaucoma cases in hospitals, often presenting asymptomatically (80%).
  • Early diagnosis of PACG is crucial to prevent vision loss, as it can cause twice as much blindness as open-angle glaucoma.

Purpose of the Study:

  • To detail the specific iris morphological changes associated with primary angle closure glaucoma (PACG).
  • To propose iris appraisal as a novel, objective, and easily performable screening method for PACG.
  • To highlight the potential of AI-powered iris analysis for mass screening in telemedicine.

Main Methods:

  • Review and description of characteristic iris patterns in PACG.
  • Comparison of iris appraisal with traditional PACG screening methods like van Herick and gonioscopy.
  • Discussion of the feasibility of using trained personnel and AI for iris-based screening.

Main Results:

  • Identified specific iris morphological alterations intrinsic to PACG.
  • Proposed iris appraisal as a potentially specific and objective screening tool.
  • Highlighted the suitability of iris analysis for telemedicine and mass screening applications.

Conclusions:

  • Iris morphology alterations are key indicators of PACG.
  • Iris appraisal offers a promising, accessible method for early PACG screening.
  • AI-driven analysis of iris patterns can facilitate widespread screening efforts for PACG.
