(Summary)
Background: Physical therapy during phase I (of)cardiac rehabilitation (CPT) can be started 12 to 24 hours after acute myocardial infarction (AMI), however, it is common to(Extend) (the) bed rest ,due to fear of (patient’s instability.).
Objective: To(asses) the hemodynamic and autonomic responses to post-AMI patients (when subjected to) 1st day of phase I protocol of CPT, as well as their safety.
Methods: We studied 51 patients with first uncomplicated AMI, 5511 years, 76% men. (The Patients were subjected to )1st day protocol phase I CPT, on average, 24 hours after AMI. The Instantaneous heart rate (HR) and RR interval were acquired by HR monitor (PolarS810i) and blood pressure (BP) checked by auscultation. HR variability was analyzed in the time (RMSSD and RMSM-Ri in ms) and frequency domains. Power spectral density was expressed in absolute (ms2/Hz) and normalized (nu) units for the bands of low (LF) and high frequencies (HF) and as LF/HF ratio.
Results: The RMSSD, HF and HFnu ( have )reduced performance of the exercises in relation to rest and post-exercise (P<0.05), LFnu and LF/HF ratio increased (P<0.05). HR and systolic BP showed an increase during the execution of the exercises in relation to rest (P<0.05). There were no any signs and/or symptoms of exercise intolerance.
Conclusions: The exercise was effective, because it caused changes hemodynamic and autonomic modulation in these patients, without causing any medical complications.

Resumo
Fundamento: A fisioterapia na fase I da reabilitação cardiovascular (FTCV) poder ser iniciada de 12 a 24 horas após o infarto agudo do miocárdio (IAM), no entanto, é comum o repouso prolongado no leito devido ao receio de instabilização do paciente. Objetivo: Avaliar as respostas autonômicas e hemodinâmicas de pacientes pós-IAM submetidos ao 1º dia de protocolo de FTCV fase I, bem como, sua segurança.
Métodos: Estudados 51 pacientes com 1o IAM não-complicado, 5511 anos, 76%
