Ablation was performed with PEF in 32 patients, RF in 23, and CRYO in 30. Peripheral venous blood samples were collected before, immediately after PVI, and the day after the procedure to measure plasma levels of S100 binding protein (S100B), high\u2010sensitivity troponin I (hsTnI), and high\u2010sensitivity troponin T (hsTnT). Groups were compared based on maximum biomarker levels and the (hsTnI\/hsTnT)\/S100B ratio as an index of cardioselectivity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Following PVI, all energy modalities caused significant myocardial injury, with PEF showing the most pronounced effects (maximum hsTnT: 1476, 958 and 967\u00a0ng\/L; maximum hsTnI: 12659, 1699 and 8109\u00a0ng\/L; for PEF, RF and CRYO, respectively). Maximum S100B levels indicating the neural impact were highest in the CRYO group (80, 80 and 190\u00a0ng\/L for PEF, RF and CRYO, respectively). PEF exhibited the greatest cardioselectivity, as indicated by the highest (hsTnI\/hsTnT)\/S100B ratio (0.11 \u00b1 0.04, 0.02 \u00b1 0.01 and 0.05 \u00b1 0.05 for PEF, RF and CRYO, respectively).
