Résumé

Objective@#and methods To investigate the correlation between temperature and heart rate, we retrospectively reviewed 249 febrile patients with documented COVID-19 patients. RB was defined as a rise in the heart rate from a basal heart rate of less than 10 beats/minute/°C rise in temperature. @*Results@#In this study, the prevalence of RB in patients with COVID-19 was 60.6%. When the HR at peak temperatures for patients with COVID-19 was compared with reference valve (general temperature–heart rate response in infectious disease), our findings demonstrate a relatively lower heart rate at all peak temperatures recorded. Despite differences in heart rate response, there were not significant differences in clinical outcomes (pulmonary manifestation, intensive care unit admission, death). @*Conclusion@#Most patients with COVID-19 are associated with relative bradycardia, not related to clinical outcomes. RB in COVID-19 can be considered as the clinical features for differential diagnosis from other febrile conditions.

Résumé

BACKGROUND AND OBJECTIVES: Wall shear stress contributes to atherosclerosis progression and plaque rupture. There are limited studies for statin as a major contributing factor on whole blood viscosity (WBV) in patients with acute coronary syndrome (ACS). This study investigates the effect of statin on WBV in ACS patients. SUBJECTS AND METHODS: We prospectively enrolled 189 consecutive patients (mean age, 61.3±10.9 years; 132 males; ST-segment elevation myocardial infarction, n=52; non-ST-segment elevation myocardial infarction, n=84; unstable angina n=53). Patients were divided into two groups (group I: previous use of statins for at least 3 months, n=51; group II: statin-naïve patients, n=138). Blood viscosities at shear rates of 1 s-1 (diastolic blood viscosity; DBV) and 300 s-1 (systolic blood viscosity; SBV) were measured at baseline and one month after statin treatment. Rosuvastatin was administered to patients after enrollment (mean daily dose, 16.2±4.9 mg). RESULTS: Baseline WBV was significantly higher in group II ([SBV: group I vs group II, 40.8±5.9 mP vs. 44.2±7.4 mP, p=0.003], [DBV: 262.2±67.8 mP vs. 296.9±76.0 mP, p=0.002]). WBV in group II was significantly lower one month after statin treatment ([SBV: 42.0±4.7 mP, p=0.012, DBV: 281.4±52.6 mP, p=0.044]). However, low-density lipoprotein cholesterol level was not associated with WBV in both baseline (SBV: R2=0.074, p=0.326; DBV: R2=0.073, p=0.337) and after one month follow up (SBV: R2=0.104, p=0.265; DBV: R2=0.112, p=0.232). CONCLUSION: Previous statin medication is an important determinant in lowering WBV in patients with ACS. However, one month of rosuvastatin decreased WBV in statin-naïve ACS patients.

Résumé

Drug-eluting stent implantation is an effective treatment for coronary artery disease, yet unexpected serious complications during stent implantation are possible. A 70-year-old man with unstable angina presented with a left main bifurcation lesion. Two drug-eluting stents were successfully deployed at the left main bifurcation lesion by the mini-crush technique under intravascular ultrasound guidance. However, after removal of the wire and intravascular ultrasound catheter, the stent of the proximal left circumflex artery was damaged and shortened at the distal edge. We used a looping wire technique to cross the injured stent and we successfully re-dilated the damaged portion of the stent. Finally, we deployed an additional drug-eluting stent at the left circumflex artery over the damaged stent. Our case illustrates the importance of gentle handling of devices during coronary intervention. Furthermore, interventionists should keep in mind the role of intravascular ultrasound when treating this kind of serious complication.
