OBJECTIVE Determine the myocardial perfusion characteristics in obstructive sleep apnea and its possible role in cardiovascular damage. METHODS AND PROCEDURES Fourteen patients from the Obesity Clinic weighing less than 130 kg underwent myocardial perfusion studies using single photon emission computed tomography with technetium 99m-labeled sestamibi(More)
UNLABELLED Myasthenia gravis (MG) is a disease characterized by the presence of acetylcholine receptor-directed autoantibodies. Functional cardiac disorders are the most common since there is no neuro-muscular plate in the heart. Autonomic nervous system is involved in MG, but the cardiac manifestations of such an involvement remain unclear. Previous EKG(More)
BACKGROUND Neurocardiogenic (vasovagal) syncope occurs frequently and can be diagnosed with the head-up tilt table (HUTT) test. Our objective in this study was to identify clinical predictors of the positivity of HUTT test in neurocardiogenic syncope. METHODS We conducted a prospective study of 117 cases (81 women and 36 men, 13-85 years of age) referred(More)
OBJECTIVE Postprandial hypotension is a known cause of syncope in the elderly. Its prevalence is unknown in our country. METHODS A prospective cross-sectional study was performed to determine PPH's Prevalence in elderly adults of both an urban and a rural Community in the State of Queretaro. Blood pressure measurements included a basal pre-prandial(More)
We present the case of a 52 year-old male with a history of C-hepatitis and two liver neoplastic lesions treated by radiofrequency (RF) ablation. The patient wears an abdominally-implanted unipolar VVI pacemaker that did not show any signs of interference during RF pulses. We describe the procedure performed and discuss the present knowledge regarding the(More)
UNLABELLED GIK solutions improve detection of myocardium viability after acute infarction because they could change the metabolic conditions, improving myocardial perfusion defects. METHODS AND RESULTS Seventy four patients (52 men, 22 women, mean age 53.3.08 +/- 12.14 years) with previous myocardial infarction (evolution time, 4.2 +/- 3.1 months)(More)
Sudden death is defined as the death occurring less than one hour before the onset of the patient's symptoms. It is a severe condition considered a public health issue in several countries and in ours, it accounts for 33 000 to 53 000 annual deaths mainly related to ischemic heart disease. The main cause of sudden death are severe ventricular arrhythmias,(More)
This response discusses the article by Kim and colleagues entitled "endoscopic clip closure versus surgery for the treatment of iatrogenic colon perforations developed during diagnostic colonoscopy: a review of 115,285 patients". Iatrogenic colonoscopic perforation, although uncommon, implies serious management problems for endoscopists and surgeons.(More)
INTRODUCTION Trauma is a leading cause of death and disability in Mexico. Unintentional injuries, along with diabetes and heart disease, contribute to > 35% of the country's total mortality. Effective and efficient prehospital care of the conditions may improve outcomes. OBJECTIVE The objective of this paper was to determine if prehospital field(More)
BACKGROUND Syncope is a common symptom and in most cases it is of a neurally mediated origin. Such patients have to be studied with a careful history and a physical exploration that should include simple maneuvers such as blood pressure (BP) recordings in decubitus and standing position. These tools can suggest diagnosis in a good percentage of patients(More)
