Baseline characteristics and CMR parameters were compared between patients with and without LV thrombus. Factors associated with LV thrombus were identified using univariable and multivariable logistic regression analyses.Among the 317 patients included in this study, 88 (27.8%) had LV thrombus. Patients with LV thrombus demonstrated a higher prevalence of heart failure, lower left ventricular ejection fraction, and greater volume, mass, and global extent of late gadolinium enhancement (LGE). They also exhibited distinct LV aneurysm characteristics, such as a larger maximum transverse dimension (maximum width), a wider aneurysm neck, and a higher aneurysm shape index (ratio of maximum length to neck width).

Consequently, sample material for each assay is often highly limited, necessitating the downscaling of methods to work with just a few micrograms of platelet protein.Here, we present a novel sample preparation platform for proteomics analysis using only 3 μg of purified platelet protein, corresponding to 2 × 10⁶ platelets, which can be obtained from approximately 2 to 8 μL of blood from a healthy individual (1.5 × 10⁵-4.5 × 10⁵ platelets/μL) or approximately 100 μL of blood from a patient with severe thrombocytopenia (<2 × 10⁴ platelets/µL).Using this platform, we detected a significant fraction of key players in the platelet activation cascade and, most importantly, identified 36 clinically relevant platelet disease markers even with a non-state-of-the art instrument. This makes LC-MS-based proteomics a highly attractive alternative to conventional assays, which often require milliliters of blood. Our platform transitions from our previously established 96-well proteomics workflow (PF96), which has been successfully employed in numerous platelet proteomics studies, into the 384-well format. This transition is accompanied by (1) a more than two-fold increase in sensitivity, (2) improved reproducibility, (3) a four-fold increase in throughput, allowing 1,536 samples to be processed per lab worker per week, and (4) reduced sample preparation costs.Thus, LC-MS-based platelet proteomics offers a compelling alternative to immunoaffinity assays (which depend on antibody availability and quality), as well as to genomic assays (which can only reveal genotypes).
