Insights
Depression worsens cardiovascular disease (CVD) prognosis. This review highlights how platelet activation, influenced by depression-related molecules, triggers cardiovascular complications, revealing a critical link.
Area of Science:
- Cardiology
- Psychiatry
- Molecular Biology
Background:
- Depression is a significant cause of morbidity and reduced quality of life in cardiovascular disease (CVD) patients.
- Depression is an independent risk factor for major adverse cardiovascular events.
- A cross-vulnerability exists between depression and CVD, where each condition worsens the other's prognosis.
Purpose of the Study:
- To dissect the mechanisms linking depression and CVD.
- To highlight the critical role of platelet behavior during depression in triggering cardiovascular complications.
- To discuss the relationship between depression and CVD-related molecules impacting platelet activation.
Main Methods:
- Literature review focusing on the interplay between depression and CVD.
- Analysis of proposed mechanisms linking the two conditions.
- Emphasis on platelet activation as a key mediator.
Main Results:
- Platelet activation is a central mechanism in the depression-CVD interplay.
- Depression influences molecules (e.g., catecholamines, adipokines, lipids, ROS, chemokines) implicated in CVD.
- These molecules impact platelet activation, potentially triggering cardiovascular events.
Conclusions:
- Platelet behavior during depression is a critical factor in cardiovascular complications.
- Understanding the molecular mechanisms linking depression and CVD, particularly platelet activation, is crucial for improving patient outcomes.
Abstract:
Depression is a major cause of morbidity and low quality of life among patients with cardiovascular disease (CVD), and it is now considered as an independent risk factor for major adverse cardiovascular events. Increasing evidence indicates not only that depression worsens the prognosis of cardiac events, but also that a cross-vulnerability between the two conditions occurs. Among the several mechanisms proposed to explain this interplay, platelet activation is the more attractive, seeing platelets as potential mirror of the brain function. In this review, we dissected the mechanisms linking depression and CVD highlighting the critical role of platelet behavior during depression as trigger of cardiovascular complication. In particular, we will discuss the relationship between depression and molecules involved in the CVD (e.g., catecholamines, adipokines, lipids, reactive oxygen species, and chemokines), emphasizing their impact on platelet activation and related mechanisms.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
