BackgroundRecent analyses in a registry of hypertensive patients suggested that preceding left ventricular (LV) hypertrophy (LVH) and/or carotid atherosclerosis are associated with incident type 2 diabetes, independent of confounders. We assess the relation between prevalent cardio-renal target organ damage (TOD) and subsequent incident type 2 diabetes in a population-based study with high prevalence of obesity.MethodsWe selected 2887 non-diabetic participants from two cohorts of the Strong Heart Study (SHS). Clinical exam, laboratory tests and echocardiograms were performed. Adjudicated TODs were LVH, left atrium (LA) dilatation, and high urine albumin/creatinine ratio (UACR). Multivariable logistic regression models were used to identify variables responsible for the association between initial TODs and incident diabetes at 4-year follow-up (FU).ResultsAfter 4 years, 297 new cases of diabetes (10%) were identified, 216 of whom exhibited baseline impaired fasting glucose (IFG, 73%, p < 0.0001). Participants developing type 2 diabetes exhibited higher inflammatory markers, fat-free mass and adipose mass and higher prevalence of initial LVH and LA dilatation than those without (both p < 0.04). In multivariable logistic regression, controlling for age, sex, family relatedness, presence of arterial hypertension and IFG, all three indicators of TOD predicted incident diabetes (all p < 0.01). However, the effects of TOD was offset when body fat and inflammatory markers were introduced into the model.ConclusionsIn this population-based study with high prevalence of obesity, TOD precedes clinical appearance of type 2 diabetes and is related to the preceding metabolic status, body composition and inflammatory status.

“…LV dilation and left atrium (LA) dilation were also eyeball evaluated . Whenever possible, LA was considered dilated if anteroposterior diameter (in the parasternal long‐axis view) was visually estimated to be >4 cm in both genders (Figure ) . All FoCUS findings and a random sample of LUS were reviewed by another emergency physician, who was blind to the final patient's diagnosis, to analyze inter‐observer variability.…”

The IVC was evaluated in subcostal view for the presence of dilatation (visually estimated to be >2 cm) and hypo-reactivity with breathing (variation of size <50% about).…”

“…Left atrium (LA) dilation is also eyeball evaluated . Whenever possible, LA is considered dilated if anteroposterior diameter (in the parasternal long‐axis view) is visually estimated to be >4 cm in both genders . The combined presence of bilateral interstitial syndrome and/or effusion and either dilated left atrium or ejection fraction ≤ 40% or both has excellent accuracy for identification of patients with acute heart failure.…”

Point‐of‐care ultrasound is a useful tool for clinicians in the management of patients. Particularly in emergency department, the role of point‐of‐care ultrasound is strongly increasing due to the need for a rapid assessment of critically ill patients and to speed up the diagnostic process. Hand‐carried ultrasound devices are particularly useful in emergency setting and allow rapid assessment of patient even in prehospital setting. This article will review the role of point‐of‐care ultrasonography, performed with pocket‐size devices, in the management of patients presenting with acute onset of undifferentiating dyspnea, chest pain, and shock in emergency department.
