RESUMO

Background: In outpatient center-based cardiac rehabilitation (O-CBCR), moderate-intensity continuous training (MICT) based on the anaerobic threshold (AT) determined by cardiopulmonary exercise stress testing is recommended. However, it is unclear whether differences in exercise intensity within the MICT domain affect peak oxygen uptake (%peakV̇O2). Methods and Results: We retrospectively evaluated patients who underwent O-CBCR at Japan Community Healthcare Organization Osaka Hospital. Those treated with the constant-load method were designated as Group A (n=38), whereas those treated with the variable-load method were designated as Group B (n=48). Although the change in exercise intensity was significantly greater in Group B by approximately 4.5 W, the change in %peakV̇O2 was not significantly different between groups. Group A had a significantly longer exercise time than Group B (by approximately 4-5 min). No deaths or hospitalizations occurred in either group. The percentage of episodes with exercise cessation was similar between the 2 groups, but the percentage of episodes with load reduction was significantly higher in Group B, mostly because of the increased heart rate. Conclusions: In supervised MICT based on AT, the variable-load method increased exercise intensity more than the constant-load method without severe complications, but did not improve %peakV̇O2.

RESUMO

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a relatively rare inherited arrhythmic disease that causes sudden cardiac death, and is caused by mutations in the cardiac ryanodine receptor (RyR2) or sarcoplasmic reticulum protein calsequestrin 2 gene (CASQ2). A 16-year-old man was diagnosed with CPVT and was implanted with a Subcutaneous-implantable Cardioverter Defibrillator (S-ICD), but defibrillation electrode detachment occurred early after placement. We suspected that a two-incision technique was the possible cause. We also report on changes in surface ECG in remote monitoring of the device. TAKE HOME MESSAGE  Although two-incision techniques are becoming the mainstream method of S-ICD implantation, we should consider that the three-incision technique may be advantageous in highly active patients. Remote monitoring may also be useful for early detection of S-ICD dislodgement.

RESUMO

A 60-year-old man developed acute myocardial infarction from the total occlusion of the right coronary artery via metastatic squamous lung cancer and was treated with percutaneous coronary intervention (PCI). Computed tomography and transthoracic echocardiography (TTE) revealed a metastatic tumor, and three-dimensional TTE was useful for determining the size and location of the tumor in relation to the coronary artery. Six months after PCI, the patient died, and an autopsy confirmed extensive metastasis to the heart and nearby vessels as detected by three-dimensional TTE. Although rare, lung cancer metastasis to the heart may directly occlude the coronary artery.

RESUMO

Atrial fibrillation (AF) is an irregular and often rapid heart rate that can increase the risk of stroke, heart failure, and other heart-related complications. Its incidence increases with age and the presence of concomitant heart disease. We present the cases of a 93-year-old woman, an 82-year-old man, and an 87-year-old woman who developed AF tachycardia. This report highlights the use of a bisoprolol transdermal patch to treat AF tachycardia in 3 adult elderly patients. In this paper, we report an initial treatment strategy using a bisoprolol transdermal patch and show heart rate trends for 24 hours.

RESUMO

A 69-year-old female suffering from third-degree atrioventricular block with syncope underwent permanent pacemaker implantation. However, she developed shortness of breath 2 months after the implantation. Blood tests revealed elevated levels of LDH, CRP, BNP, and SIL-2R. Transthoracic echocardiography showed thickened left and right atrial walls with mild pericardial effusion. A diagnosis was made based on a CT scan and histology. Although most primary cardiac malignant lymphomas are associated with a poor prognosis, the patient was treated successfully with chemotherapy.
