Magnetic Resonance for Differential Diagnosis of Left Ventricular Hypertrophy: Diagnostic and Prognostic Implications.

BACKGROUND: Left ventricular hypertrophy (LVH) may be due to different causes, ranging from benign secondary forms to severe cardiomyopathies. Transthoracic Echocardiography (TTE) and ECG are the first-level examinations for LVH diagnosis. Cardiac magnetic resonance (CMR) accurately defines LVH type, extent and severity. OBJECTIVES: to evaluate the diagnostic and prognostic role of CMR in patients with TTE and/or ECG evidence of LVH. METHODS: We performed CMR in 300 consecutive patients with echocardiographic and/or ECG signs of LVH. RESULTS: Overall, 275 patients had TTE evidence of LVH, with initial suspicion of hypertrophic cardiomyopathy (HCM) in 132 (44%), cardiac amyloidosis in 41 (14%), hypertensive LVH in 48 (16%), aortic stenosis in 4 (1%), and undetermined LVH in 50 (16%). The initial echocardiographic diagnostic suspicion of LVH was confirmed in 172 patients (57.3%) and changed in 128 patients (42.7%, p < 0.0001): the diagnosis of HCM increased from 44% to 71% of patients; hypertensive and undetermined LVH decreased significantly (respectively to 4% and 5%). CMR allowed for a diagnosis in 41 out of 50 (82%) patients with undetermined LVH at TTE. CMR also identified HCM in 17 out of 25 patients with apparently normal echocardiography but with ECG criteria for LVH. Finally, the reclassification of the diagnosis by CMR was associated with a change in survival risk of patients: after CMR reclassification, no events occurred in patients with undetermined or hypertensive LVH. CONCLUSIONS: CMR changed echocardiographic suspicion in almost half of patients with LVH. In the subgroup of patients with abnormal ECG, CMR identified LVH (particularly HCM) in 80% of patients. This study highlights the indication of CMR to better characterize the type, extent and severity of LVH detected at echocardiography and suspected with ECG.

The core components of cardio-oncology rehabilitation.

The increased efficacy of cancer therapy has resulted in greater cancer survival and increasing number of people with cancer and cardiovascular diseases. The sharing of risk factors, the bidirectional relationship between cancer and cardiovascular diseases and the cardiotoxic effect of chemotherapy and radiotherapy, are the cause of the rapid expansion of cardio-oncology. All strategies to preserve cardiovascular health and mitigate the negative effect of cancer therapy, by reducing the cardiovascular risk, must be pursued to enable the timely and complete delivery of anticancer therapy and to achieve the longest remission of the disease. Comprehensive cardiac rehabilitation is an easy-to-use model, even in cancer care, and is the basis of Cardio-Oncology REhabilitation (CORE), an exercise-based multi-component intervention. In addition, CORE, besides using the rationale and knowledge of cardiac rehabilitation, can leverage the network of cardiac rehabilitation services to offer to cancer patients exercise programs, control of risk factors, psychological support, and nutrition counseling. The core components of CORE will be discussed, describing the beneficial effect on cardiorespiratory fitness, quality of life, psychological and physical well-being, and weight management. Furthermore, particular attention will be paid to how CORE can counterbalance the negative effect of therapies in those at heightened cardiovascular risk after a cancer diagnosis. Barriers for implementation, including personal, family, social and of the health care system barriers for a widespread diffusion of the CORE will also be discussed. Finally, there will be a call-to-action, for randomized clinical trials that can test the impact of CORE, on morbidity and mortality.

Impact of a clinical microbiology-intensive care consulting program in a cardiothoracic intensive care unit.

A preintervention-postintervention study was carried out over a 4-year period to assess the impact of an antimicrobial stewardship intervention, based on clinical microbiologist ward rounds (clinical microbiology-intensive care partnership [CMICP]), at a cardiothoracic intensive care unit. Comparison of clinical data for 37 patients with diagnosis of bacteremia (18 from preintervention period, 19 from postintervention period) revealed that CMICP implementation resulted in (1) significant increase of appropriate empirical treatments (+34%, P = .029), compliance with guidelines (+28%, P = .019), and number of de-escalations (+42%, P = .032); and (2) decrease (average = 2.5 days) in time to optimization of antimicrobial therapy and levofloxacin (Δ 2009-2012 = -74 defined daily dose [DDD]/1,000 bed days) and teicoplanin (Δ 2009-2012 = -28 DDD/1,000 bed days) use.

Symptoms and signs of tear film dysfunction in glaucomatous patients.

PURPOSE: The purposes of this study were to evaluate the presence of symptoms of tear film dysfunction by using the Ocular Surface Disease Index (OSDI) questionnaire in glaucomatous patients and to examine whether they have ocular surface signs. METHODS: Fifty patients with ocular hypertension or open-angle glaucoma were sequentially examined. All patients used preserved antiglaucomatous drops once, twice, 3 times, or 4 times a day. Each patient filled out an OSDI questionnaire. Fluorescein corneal staining, lissamine green conjunctival staining, break-up time, and Schirmer I test were performed in patients with positive OSDI. RESULTS: Using the OSDI, 26 of 50 patients (52%) showed at least mild symptoms of tear film dysfunction (score >12); of them, 17 (34%) had severe OSDI (Score >32). Decrease in tear production was seen in only 8 glaucomatous patients. The break-up time was <7 s in 18 patients. Lissamine green conjunctival staining was positive in at least one eye of all the 26 patients, whereas fluorescein corneal staining was positive in at least one eye of 22 patients. A statistically significant (P<0.05) difference was found for lissamine green conjunctival staining between 16 patients using ipotensive drops once or twice a day and 10 patients using drops 3 or 4 times a day. In the group of patients using only ß-blocker agents, we found a positive correlation between symptoms and vital staining of the ocular surface. CONCLUSION: Fifty-two percent of patients in therapy with preserved antiglaucomatous drops showed symptoms of tear film dysfunction. Signs of ocular surface diseases seemed to be greater in patients under >2 medications. Symptoms correlated to signs only in patients in monotherapy with ß-blockers drops.
