RESUMO
PURPOSE OF REVIEW: The review is focused on "digital health", which means advanced analytics based on multi-modal data. The "Health Care Internet of Things", which uses sensors, apps, and remote monitoring could provide continuous clinical information in the cloud that enables clinicians to access the information they need to care for patients everywhere. Greater standardization of acquisition protocols will be needed to maximize the potential gains from automation and machine learning. RECENT FINDINGS: Recent artificial intelligence applications on cardiac imaging will not be diagnosing patients and replacing doctors but will be augmenting their ability to find key relevant data they need to care for a patient and present it in a concise, easily digestible format. Risk stratification will transition from oversimplified population-based risk scores to machine learning-based metrics incorporating a large number of patient-specific clinical and imaging variables in real-time beyond the limits of human cognition. This will deliver highly accurate and individual personalized risk assessments and facilitate tailored management plans.

Telemedicine has deeply innovated the field of emergency cardiology, particularly the treatment of acute myocardial infarction. The ability to record an ECG in the early prehospital phase, thus avoiding any delay in diagnosing myocardial infarction with direct transfer to the cath-lab for primary angioplasty, has proven to significantly reduce treatment times and mortality. This consensus document aims to analyse the available evidence and organizational models based on a support by telemedicine, focusing on technical requirements, education, and legal aspects.
RESUMO
Manual therapists apply physical interventions to the entire structure of the body to promote healing, prevent pathologies, and improve patient health. In osteopathic practice, palpatory evaluation is considered a fundamental clinical practice requirement for identifying somatic dysfunction. Most of the articles published in this area have failed to demonstrate a level of reproducibility that supports palpation in evidence-based clinical practice. When considering the poor reliability of the palpatory tests highlighted in the literature, a discrepancy is noted with what is known about the tactile sensitivity of human hands. For static touch, the minimum size that can be detected, in the absence of applied movement or vibration, is approximately 0.2 mm. Yet, it seems that this high level of precision is insufficient to ensure reliability in the tests used to evaluate osteopathic somatic dysfunction. The purpose that underscores this article is to determine how these two contradictory elements, high sensitivity and low reliability, can be present in palpatory tests. The article reports the literature findings regarding palpatory tests of pelvic, which is an important structure for clinical purposes. Additionally, a critical review of how these studies were conducted is provided to identify any elements that may justify the obtained results. Following recent accredited guidelines present in the literature, we propose suggestions on vision training methods, manual perception refinement training, the search for anatomical markers, and the position of the examiner in relation to the examinee that may be useful for future studies on the topic covered by the article.
RESUMO
Technological innovation provides easily accessible tools capable of simplifying healthcare processes. Notably, digital technology application in the cardiology field can improve prognosis, reduce costs, and lead to an overall improvement in healthcare. The digitization of health data, with the use of electronic health records and of electronic health files in Italy, represents one of the fields of application of digital technologies in medicine. The 2023 States General of the Italian Association of Hospital Cardiologists (ANMCO) provided an opportunity to focus attention on the potential benefits and critical issues associated with the implementation of the aforementioned digital tools, artificial intelligence, and telecardiology. This document summarizes key aspects that emerged during the event.

There is a preponderance of evidence that, in the setting of an acute coronary syndrome, an invasive approach using coronary revascularization has a morbidity and mortality benefit. However, recent stable ischemic heart disease (SIHD) randomized clinical trials testing whether the addition of coronary revascularization to guideline-directed medical therapy (GDMT) reduces death or major cardiovascular events have been negative. Based on the evidence from these trials, the primary role of GDMT as a front line medical management approach has been clearly defined in the recent SIHD clinical practice guideline; the role of prompt revascularization is less precisely defined. Based on data from observational studies, it has been hypothesized that there is a level of ischemia above which a revascularization strategy might result in benefit regarding cardiovascular events. However, eligibility for recent negative trials in SIHD has mandated at most minimal standards for ischemia. An ongoing randomized trial evaluating the effectiveness of randomization of patients to coronary angiography and revascularization as compared to no coronary angiography and GDMT in patients with moderate-severe ischemia will formally test this hypothesis. The current review will highlight the available evidence including a review of the published and ongoing SIHD trials.

AIMS: To determine whether short-term treatment with trimetazidine (TMZ), an antiischemic agent that directly inhibits fatty acid oxidation and results in stimulation of glucose oxidation, may improve myocardial perfusion and left ventricular systolic function in diabetic patients with ischemic cardiomyopathy. METHODS AND RESULTS: We studied 34 clinically stable patients with type 2 diabetes mellitus (DM) and documented multivessel coronary artery disease (29 men and 5 women, mean age 54 +/- 9 years) with depressed systolic function (left ventricular ejection fraction 38 +/- 6%). Patients were randomized into two groups. One group received TMZ (20 mg tid) for 3 months (n = 19), while another group received a placebo during the same period (n = 15). On study entry and at 3 months, all patients underwent a gated Single Photon Emission Computed Tomography (SPECT) myocardial scintigraphy with a 2-day stress(Bruce)-rest protocol (500 MBq tetrofosmin). At 3 months, TMZ-treated patients had a significant improvement in systolic wall thickening (P < 0.05) and ejection fraction (P = 0.007) as compared with control patients. These effects were more marked in patients with more severe reversible perfusion defects on initial evaluation and were not associated with changes in myocardial defects (P = 0.38). Total exercise time was also improved in TMZ-treated patients (20.5%, P < 0.05 vs. controls). CONCLUSIONS: In diabetic cardiomyopathy, short-term TMZ improved left ventricular systolic function and functional capacity despite no change in myocardial perfusion. These benefits were more evident in patients with more severe perfusion defects on initial evaluation, suggesting that chronic myocardial ischemia is a requirement for the effects of TMZ on left ventricular systolic performance.

UNLABELLED: The aim of this study was to investigate whether early (time 1, or T1) myocardial tetrofosmin imaging is feasible and as accurate in detecting coronary artery disease as is standard delayed (time 2, or T2) imaging. METHODS: One hundred twenty patients (100 men and 20 women; mean age +/- SD, 61 +/- 10 y) with anginal symptoms underwent tetrofosmin gated SPECT. Stress/rest T1 imaging was performed at 15 min and T2 at 45 min after injection. Image quality was visually evaluated using a 4-point scale (from 0 = poor to 3 = optimal). Myocardial perfusion analysis was performed on a 20-segment model using quantitative perfusion SPECT software, and reversible ischemia was scored as a summed difference score (SDS). Coronary angiography was performed within 1 mo on all patients, and stenosis of more than 50% of the diameter was considered significant. RESULTS: Overall, quality was scored as optimal or good for 94% of T1 images and 95% of T2 images (P = not statistically significant). Heart, lung, liver, and subdiaphragmatic counts did not differ for stress and rest T1 and T2 imaging. A good linear relationship was seen between T1 and T2 SDS (r = 0.69; P < 0.0001), and Bland-Altman analysis showed good agreement between the 2 conditions. In terms of global diagnostic accuracy, areas under the receiver-operating-characteristic curve were comparable between T1 and T2 (0.80 vs. 0.81, P = not statistically significant). Discrepancies between T1 and T2 SDS were observed in 44% of patients (T1 - T2 SDS > 2). Linear regression analysis showed a good correlation between T1 and T2 SDS (r = 0.67; P < 0.0001), whereas the Bland-Altman method showed a shift in the mean value of the difference of +2.67 +/- 2.73. In patients with a T1 - T2 SDS of more than 2, areas under the receiver-operating-characteristic curves were significantly higher for T1 than for T2 images (0.79 vs. 0.70, P < 0.001). CONCLUSION: T1 imaging is feasible and as accurate as T2 imaging in identifying coronary artery disease. However, in a discrete subset of patients, early acquisition strengthens the clinical message of defect reversibility by permitting earlier, more accurate identification of more severe myocardial ischemia.

The use of telemonitoring and telemedicine is a relatively new but quickly developing area in medicine. As new digital tools and applications are being created and used to manage medical conditions such as heart failure, many implications require close consideration and further study, including the effectiveness and safety of these telemonitoring tools in diagnosing, treating and managing heart failure compared to traditional face-to-face doctor-patient interaction. When compared to multidisciplinary intervention programs which are frequently hindered by economic, geographic and bureaucratic barriers, non-invasive remote monitoring could be a solution to support and promote the care of patients over time. Therefore it is crucial to identify the most relevant biological parameters to monitor, which heart failure sub-populations may gain real benefits from telehealth interventions and in which specific healthcare subsets these interventions should be implemented in order to maximise value.
