Purpose: Cardiovascular diseases are the major cause of death in subjects with chronic spinal cordy injury (SCI). Interestingly, SCI subjects present higher carotid intima-media thickness (IMT) and worse diastolic function than able-bodied individuals, independent of traditional cardiovascular risk factors. The present study investigated the relationship between carotid and echocardiographic measurements and Ambulatory Blood Pressure Monitoring (ABPM) in SCI patients.

Methods: Thirty two normotensive, nondiabetic, nonsmoker and normolipemic SCI men were enrolled (16 tetraplegic and 16 paraplegic, age 31.9±1.3 years, injury time 6.8±0.8 years) and underwent clinical, laboratory, ABPM, conventional echocardiography, tissue doppler and ultrasound carotid analysis. Data were evaluated by univariate and linear regression analyses and are presented as mean ± standard error. A p-value of less than 0.05 was considered significant.

Results: ABPM measurements in 24 hours were 108.8±1.3 X 64.1±1.3 mmHg and only 12 subjects (38%) exhibited nocturnal dipping. No participant exhibited features of autonomic dysreflexia. Univariate analysis revealed that 24-hour ABPM values correlated with carotid IMT, but not with echocardiographic or tissue doppler parameters. In this context, 24-hour diastolic BP was the variable showing the strongest correlation with IMT (r=0.54; p=0.002). Conversely, casual BP measurements, age, body mass index, serum lipid profile, glucose and C-reactive protein did not correlate with neither carotid nor cardiac measurements. Linear regression analysis adjusted for injury level and nocturnal dipping status showed that 24-hour diastolic BP was independently associated with carotid IMT (B=0.417±0.193; p=0.018).

Conclusions: These data demonstrate that subclinical atherosclerosis is directly related to ABPM values in SCI individuals, suggesting that hemodynamic stimuli may play a role in the physiopathogenesis of arterial remodeling in SCI subjects even within normal BP range.

Carotid Plaque Burden as a Measure of Subclinical Atherosclerosis

.

Results  The mean age was 68.8 years, and 65.3% of subjects had intermediate Framingham Risk Score (6% to 20% 10-year risk). Carotid plaques were identified in 78% of cases, abnormal ABI in 10%, AAD >20 mm in 28%, and coronary calcium in 68% of participants. Carotid plaque burden was found to correlate stronger with CACS (chi-square 450, p < 0.0001) than did cIMT (chi-square 24, p < 0.0001), AAD (chi-square 2.9, p = 0.091), and ABI (chi-square 35.2, p < 0.0001).
Conclusions  In the BioImage study, a new 3-dimensional–based ultrasound method identified more carotid plaques than in previous studies. Compared to other methods, carotid plaque burden was the strongest cross-sectional predictor of CACS, and its clinical utility as predictor of future cardiovascular events is being evaluated in the BioImage study.

Geometric Assessment of Asymmetric Septal Hypertrophic Cardiomyopathy by CMR

.
.
Conclusions  Using 3D analysis, we found that the majority of patients with asymmetrical septal HCM in fact showed a spiral pattern of HT following a counterclockwise (or “left-handed”) spiral trajectory. The variation in magnitude of rotation among patients, however, was highly variable.

Isso sim, é uma Mitral!


.
Analisando apenas a imagem à direita, fica bem claro que o uso do 3D irá revolucionar a ecocardiografia.
.
Nessa revolução, novas tabelas de normalidade irão surgir. Tanto para cavidades como para funcional de válvulas e ventrículos.
.
Como analisar a imagem acima pensando em dois palitos se mexendo, como na imagem da esquerda?
.
Abertura e fechamento são diferentes demais na modalidade 3D.
.
O que dizer da contratilidade? Usualmente confundida com “espessamento” ou expressões como “parede vem mais” ou “aproxima” ou mesmo, vejam vocês, “mexe bem”!
.
É hora de deixar o passado de lado e abrir a mente ao mundo real, que sempre foi 3D.

Safety of echocardiographic contrast in hospitalized patients with pulmonary hypertension: a multi-center study†

.
 Echocardiographic contrast (EC) improves the diagnostic accuracy of suboptimal echocardiograms. In October 2007, the Food and Drug Administration (FDA) placed a black box warning on the label of the perflutren-based agents Definity and Optison, contraindicating their use in patients with pulmonary hypertension (PHT) and unstable cardiopulmonary status, after serious cardiopulmonary reactions occurred in temporal relation to EC administration. In 2008 and 2011, the FDA revised the black box warning allowing their use in this same population. However, limited data exist regarding the safety profile of these agents in patients with PHT.
.
The study group included 1513 patients (age 69 ± 14 years, 55% males, BMI 33 ± 9 kg/m2), of which 911 (60%) had mild PHT, 515 (34%) had moderate PHT, and 87 (6%) had severe PHT. 
.
The incidence of adverse events in all subgroups was rare (0.002%) 
.
Conclusion The use of the EC agent Definity is safe in hospitalized patients with PHT.

Pelas razões acima e por muitas outras que colocam o ecocardiograma em segundo plano em relação aos outros métodos de imagem, o blog EchoTalk solicita o empenho do D.I.C e de todos os ecocardiografistas para a volta da venda de microbolhas no país.
