Insights

The platelet-to-lymphocyte ratio (PLR) is elevated in patients with mitral annular calcification (MAC). Higher PLR levels are independently associated with the presence of MAC, suggesting its potential as a biomarker.

Area of Science:

  • Cardiology
  • Hematology
  • Biomarkers

Background:

  • Mitral annular calcification (MAC) shares risk factors and pathogenesis with atherosclerosis.
  • Increased platelet-to-lymphocyte ratio (PLR) is linked to atherosclerotic diseases.

Purpose of the Study:

  • To investigate the association between PLR levels and the presence of MAC.
  • To determine if PLR can serve as a biomarker for MAC.

Main Methods:

  • A cohort of 1060 patients (704 with MAC, 356 without) was analyzed.
  • Demographic, clinical, and laboratory data, including complete blood count for PLR calculation, were collected.
  • Statistical analysis identified independent predictors of MAC.

Main Results:

  • Patients with MAC were older and had higher rates of hypertension.
  • Mean PLR was significantly higher in the MAC-positive group (129.1 vs 103.5, p < 0.001).
  • PLR, along with age, hypertension, and NLR, was independently associated with MAC presence (OR: 1.109).

Conclusions:

  • PLR is significantly increased in patients with MAC.
  • PLR is an independent predictor of MAC presence.
  • Elevated PLR may indicate an increased risk or presence of MAC.

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Mitral Valve Prolapse I: Introduction

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

Mitral Regurgitation II: Clinical Features and Diagnostic Tests

Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...
