(radcliffecardiology.com)
  • 3,4 As the developed world population continues to age and the more widespread use of Doppler techniques results in detection of more (asymptomatic) patients, aortic stenosis constitutes a growing health burden. (radcliffecardiology.com)
  • If, as is often the case-particularly in older individuals-the patient presents without symptoms, hemodynamic instability, or evidence of important precipitating conditions (such as silent myocardial infarction or ischemia, decompensated heart failure, pulmonary embolus, or hemodynamically significant valvular disease), hospitalization is usually not necessary.

  • Carotid sonography and plain films of the neck were performed immediately after the procedure and then at the same time intervals. (ajnr.org)
  • In stable angina, the relationship between workload or demand and ischemia is usually relatively predictable. (msdmanuals.com)
  • The mean lifetime expectancy after onset of angina is reported to be 4.5 years, after syncope 2.6 years and after heart failure less than one year. (radcliffecardiology.com)
  • Furthermore, increased left ventricular pressure, decreased diastolic filling and decreased diastolic coronary perfusion time all contribute to ischaemia. (radcliffecardiology.com)
  • A detailed description of the series of events that leads to beta cell dysfunction and loss in human pancreatic tissues, particularly during the asymptomatic phase of human T1D, could help identify biomarkers highly specific for early T1D, and design therapeutic strategies to delay or stop the progression towards clinically overt T1D by slowing or preventing the development of beta cell-specific autoimmunity.

  • Initial screening magnetic resonance imaging (MRI) (A-C). A, A focus of restricted diffusion on diffusion-weighted imaging, with a corresponding region of decreased signal on the apparent diffusivity coefficient maps shown in panel B. These findings indicate that the cerebral ischemia occurred within the 10 days preceding the magnetic resonance imaging (MRI). (jamanetwork.com)
  • Treating the Infection Management is time sensitive, according to Dr. Miller, and this patient should be referred back to his retina specialist for a suspected scleral buckle infection. (reviewofoptometry.com)
  • Although buckle exposure is a significant risk factor for scleral buckle infection, this is not necessarily an indication for removal if the patient is asymptomatic. (reviewofoptometry.com)
  • Esmolol hydrochloride is a beta 1 -selective (cardioselective) adrenergic receptor blocking agent with rapid onset, a very short duration of action, and no significant intrinsic sympathomimetic or membrane stabilizing activity at therapeutic dosages. (nih.gov)
  • Because each of these clinical conditions involves compromise to neural structures, the concern is that further insult from surgical (eg, intraoperative stretch or compression, tourniquet ischemia, hemorrhage) or anesthetic (eg, mechanical trauma, vasoconstrictor-induced ischemia, local anesthetic toxicity) causes may result in new or worsening postoperative neurologic deficits.
