Study design and patients
Retrospect study consecutive 33 cases/patients undergo elective TVCP
placed by the first author (Meng L) for scheduled non-cardiac surgery
from August 2018 to March 2020. 22 of them have measured cardiac
biomarkers values before and after TVCP placement. Analysis of the
values changes of the cardiac
biomarkers. The Hunan Provincial People’s Hospital Ethics Committee
granted study approval (reference number: 2020-07) and waived the usual
requirement for informed consent as all data were de-identified and
analyzed anonymously.
22 eligible patients had a median age of 66 (50-83) years, and 6 (27%)
were women, 13 (59%) from the cancer center, others from hepatobiliary
surgery, general surgery, and spine surgery department. None of the
patients had history recorded of myocardial infarction, stroke, heart
failure, chronic kidney disease, anemia. No remarkable structure
abnormality findings in echocardiography. B-type natriuretic peptide
(BNP) and hemoglobin were normal. Except for slightly elevated
creatinine in 1 case (120.5umol/L), creatinine was normal. Decisions of
TVCP were made by surgeons after consultation with cardiologists or/and
anesthesiologists. Except for the bradyarrhythmia, patients with low
cardiovascular risk, so TVCP were simply placed bedside, rather than
catheter lab. TVCP indications and baseline characteristics of patients
included in table 1.
