When the worst headache becomes the worst heartache!

BACKGROUND AND PURPOSE: Although a great deal of literature has been generated regarding left ventricular wall abnormalities, ECG changes and cardiac enzyme leaks associated with subarachnoid hemorrhage (SAH), there have been only a few reports of true transient left ventricular apical ballooning syndrome in patients with SAH. Several pathophysiological mechanisms have been proposed to explain the unusual features of this syndrome, such as multivessel coronary vasospasm, abnormalities in coronary microvascular function, and catecholamine-mediated cardiotoxicity. Summary of Case- A previously healthy 64-year-old woman with no history of vascular disease was found unresponsive at home. She was taken to the emergency room where a CT head revealed an SAH due to a ruptured aneurysm of the posterior communicating artery. On admission, an ECG showed deeply inverted T-waves and QT prolongation, typical of SAH. Cardiac troponin was measured at 1.2 ng/mL, and later increased to 3.7 ng/mL. A transthoracic echocardiogram on the next day revealed a large left ventricular wall abnormality, characteristic of apical ballooning with an ejection fraction of 25% to 30%. The patient remained hemodynamically stable and was started on low dose beta-blocker and angiotensin-converting enzyme inhibitor. She had an uneventful cardiac recovery within 5 days at which time a repeat transthoracic echocardiogram revealed a normal ejection fraction with no wall motion abnormality. CONCLUSIONS: This report adds to the growing list of "stressors" for Takotsubo cardiomyopathy. Clinicians should be aware of the existence and the typical clinical manifestations of this syndrome, which is increasingly recognized in various populations. In particular, neurologists should consider this syndrome in the differential diagnosis of ECG changes and apical wall motion abnormalities in patients with SAH. Prognosis is generally very good with full recovery in most patients; however, there may be increased morbidity associated in patients with SAH.     

Free-floating thrombus of the carotid artery: literature review and case reports

BACKGROUND: Free-floating thrombus (FFT) of the carotid artery is an uncommon entity that usually presents as an acute emergency. Management is based on case reports and series because the natural history and optimal treatment are unknown. This study was conducted to systematically review the world literature in an attempt to better understand FFT, its presentation, distribution, management, and outcome. METHOD: A literature search in all languages was performed of the PubMed database (> or =1950s) and Medline database (1966-November 2004). All relevant articles were reviewed and their references analyzed in a similar manner for further literature. Cases from the authors' institutions were reviewed as well. All cases within the reports were individually assessed for inclusion or exclusion. Inclusion required that the FFT originate or anchor within the carotid artery (ie, excluding emboli, arch thrombi with extensions into the carotid artery), be partially occluding (ie, excluding occlusions, "string-sign," microscopic thrombus), and ideally have an elongated or protrusive morphology, circumferential flow around the distal portion, and cyclical motion with the cardiac cycles. RESULTS: There were 61 reports reviewed, of which 43 contained FFT cases. These reports had 342 cases (including the current series) that were reviewed, of which 145 met our inclusion criteria. A database was created for qualitative and quantitative assessment of all cases. When data were pooled, appropriate statistical analysis was performed. A limitation of the study is that FFT is under-reported and ill defined, which limited the analysis in quantity and quality. In addition, reporting is not uniform, and therefore, significant data were not always present. In attempting to define FFT and include or exclude cases, subjectivity is inherent. CONCLUSIONS: FFT is more frequently reported in men than women, with a ratio of nearly 2:1 (P < .0001), and at a younger age than in most patients with carotid disease (P < .0001 when compared with North American Symptomatic Carotid Endarterectomy Trial, European Carotid Surgery Trial, and Asymptomatic Carotid Surgery Trial). Symptoms are present in 92% of patients. There was a trend for patients with FFT to be hypercoagulable (47% of those serologically tested). The internal carotid artery was the most commonly affected (75%), with atherosclerosis being the most common associated pathology. Medical and surgical management have both been used, with neither clearly superior to the other. Medical management for stabilizing neurologic deficits has less risk and less benefit than surgical intervention.     

Care related pain in hospitalized patients: A cross‐sectional study

Context: Care‐related pain includes pain occurring during transportation, movement, diagnostic imaging, physical examination, or treatment. Its prevalence has never been assessed in a large adult inpatient population. Objective: To identify the procedures likely to induce or increase pain in hospital patients, attempting to separate the most painful from those reported as most frequently inducing pain. Design: A single‐day cross‐sectional survey conducted in two large French teaching hospitals, including all hospitalized patients, free of communication problems. One third was randomly selected and interviewed about the painful episodes that had occurred or were associated with the procedures performed during the previous two weeks. Patients were interviewed using a structured questionnaire. Results: Six‐hundred‐eighty‐four patients were randomly selected. Six‐hundred‐seventy‐one painful events were reported in 55% of the patients, with an average of 1.8events/patient. Fifty‐two percent of the painful events were associated with procedures performed by non‐medical staff; 38% of the painful episodes occurred during procedures involving vascular puncture and 24% during patients’ mobilization. In 57% of painful procedures, pain was rated as severe or extremely severe. The most painful procedures were invasive procedures, other than vascular and non vascular punctures (74% of severe and extremely severe painful episodes). Maximum pain intensity was rated higher for procedures that were repeated than for those experienced only once (62% versus 53%, p=0.02). Conclusion: This survey gives new insight into our daily practice. Proper management of care‐related pain should be a major concern of all hospital staff to improve the quality of our health care.
