Preventing severe complications such as heart failure and death remains a major priority, while maintaining the need for effective and potentially curative cancer therapy. Careful patient monitoring and early detection of cardiovascular complications may allow the timely implementation of cardioprotective strategies and treatments that could delay or prevent myocardial toxicity. Materials and Methods: A total of 92 women with breast cancer were enrolled in a prospective observational cohort study. All patients received an anthracycline-based chemotherapy regimen, cyclophosphamide, docetaxel and trastuzumab. Biomarker assessment, including NT-proBNP, high-sensitivity cardiac troponin I (hs-cTnI), Gal-3, and GDF-15, was performed at baseline and at the initiation of trastuzumab-based therapy. A comprehensive diastolic function assessment was performed, including transmitral Doppler flow parameters and tissue velocities. Patients were followed for 12 months, and all cardiovascular events occurring during the follow-up period were recorded. Results: Biological and ecocardiographic parameters were analyzed and multiple models of prediction were made. To identify predictors of estimated left ventricular filling pressure (eLVFP), stepwise multiple linear regression analyses were performed, and four significant predictors of left ventricular end-diastolic filling pressure were identified: one echocardiographic parameter (baseline LV filling pressure) and three biological variables (changes in Gal-3, GDF-15, and hs-cTnI levels after treatment). The overall regression model was highly significant (p &lt; 0.001) and explained 77.07% of the variance in the dependent variable. Gal-3 was the strongest predictor of left ventricular filling pressure (p &lt; 0.001). Conclusions: The regression analyses suggest that this phenotype is multifactorial, with echocardiographic indices capturing the functional component and circulating biomarkers reflecting complementary aspects of the underlying biological response. This multimodal approach may therefore help identify patients with early treatment-related cardiac changes and potentially those at increased risk of subsequent CTRCD, particularly during a period when conventional LVEF-based surveillance may still appear reassuring.<\/jats:p>","DOI":"10.3390\/medicina62091634","type":"journal-article","created":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T08:11:15Z","timestamp":1787731875000},"page":"1634","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Can Biomarker-Based Monitoring Detect the Early Development of Diastolic Dysfunction During Chemotherapy?"],"prefix":"10.3390","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9407-2261","authenticated-orcid":false,"given":"Anca Daniela","family":"Farca\u015f","sequence":"first","affiliation":[{"name":"Internal Medicine Department, \u201cIuliu Ha\u0163ieganu\u201d University of Medicine and Pharmacy, 400012 Cluj Napoca, Romania"},{"name":"Cardiology Department, Cluj County Emergency Clinical Hospital, 400347 Cluj Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1488-8130","authenticated-orcid":false,"given":"Cerasela Mihaela","family":"Goidescu","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, \u201cIuliu Ha\u0163ieganu\u201d University of Medicine and Pharmacy, 400012 Cluj Napoca, Romania"},{"name":"\u201cConstantin Papilian\u201d Military Emergency Clinical Hospital, 400132 Cluj Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirela Anca","family":"Stoia","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, \u201cIuliu Ha\u0163ieganu\u201d University of Medicine and Pharmacy, 400012 Cluj Napoca, Romania"},{"name":"Cardiology Department, Cluj County Emergency Clinical Hospital, 400347 Cluj Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florin Petru","family":"Anton","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, \u201cIuliu Ha\u0163ieganu\u201d University of Medicine and Pharmacy, 400012 Cluj Napoca, Romania"},{"name":"Cardiology Department, Cluj County Emergency Clinical Hospital, 400347 Cluj Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5152-6040","authenticated-orcid":false,"given":"Andrada Viorica","family":"P\u00e2rvu","sequence":"additional","affiliation":[{"name":"Oncological Department, \u201cIuliu Ha\u0163ieganu\u201d University of Medicine and Pharmacy, 400012 Cluj Napoca, Romania"},{"name":"\u201cProf. Dr. Ion Chiricu\u021b\u0103\u201d Oncology Institute Cluj, 400015 Cluj Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-9065-1745","authenticated-orcid":false,"given":"Camil Horia Eusebiu","family":"Cri\u015fan","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, \u201cIuliu Ha\u0163ieganu\u201d University of Medicine and Pharmacy, 400012 Cluj Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diana Larisa","family":"Mocan Hognogi","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, \u201cIuliu Ha\u0163ieganu\u201d University of Medicine and Pharmacy, 400012 Cluj Napoca, Romania"},{"name":"Cardiology Department, Cluj County Emergency Clinical Hospital, 400347 Cluj Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1859","DOI":"10.1042\/CS20190653","article-title":"Anthracycline-induced cardiomyopathy: Cellular and molecular mechanisms","volume":"134","author":"Dadson","year":"2020","journal-title":"Clin.
