We enrolled infants 6 to 12 weeks of age who had HIV infection (defined by a positive polymerase-chain-reaction [PCR] test for HIV-1 DNA and a plasma HIV-1 RNA level on PCR of >1000 copies per milliliter) and a CD4 percentage of 25% or more. Exclusion criteria are listed in the
Cardiomyopathies
These conditions can be inherited or acquired, and they can lead to a variety of symptoms, such as shortness of breath, fatigue, and irregular heartbeats.
Cardiomyopathies can be classified into different types based on the underlying cause and the specific changes in the heart muscle.
Reseachers and clinicians use a variety of tools and techniques to study and manage cardiomyopathies, including genetic testing, imaging studies, and medication therapies.
Understaning the latest advancements in cardiomyopathy research and treatment is crucial for providing the best possible care for patients affected by these complex and challenging conditions.

The GBD cause list is organised as a hierarchy (
For GBD 2016, we disaggregated some Level 3 causes to expand the cause hierarchy used for GBD 2015 by 18 causes of death. GBD cause list expansion was motivated by two main factors: inclusion of causes that result in substantial burden and inclusion of causes that are of high policy relevance. New causes for GBD 2016 included Zika virus disease, congenital musculoskeletal anomalies, urogenital congenital anomalies, and digestive congenital anomalies. Other leukaemia was added as a Level 4 subcause to leukaemia rather than being estimated in the Level 3 residual category of other neoplasms. The Level 3 cause of collective violence and legal intervention was separated into “executions and police conflict” and “conflict and terrorism”. Disaggregation of existing Level 3 causes resulted in the addition of 11 detailed causes at Level 4 of the cause hierarchy: drug-susceptible tuberculosis, multidrug-resistant tuberculosis, and extensively drug-resistant tuberculosis; drug-susceptible HIV–tuberculosis, multidrug-resistant HIV–tuberculosis, and extensively drug-resistant HIV–tuberculosis; alcoholic cardiomyopathy, myocarditis, and other cardiomyopathy; and self-harm by firearm, and self-harm by other means. Within each level of the hierarchy the number of collectively exhaustive and mutually exclusive causes for which the GBD study estimates fatal outcomes is three at Level 1, 21 at Level 2, 145 at Level 3, and 212 at Level 4. For GBD 2016, separate estimates were developed for a total of 264 unique causes and cause aggregates.

All participants were divided into 2 groups, the death group and the non-death group, according to the prognosis data obtained 30 days after onset.
The Wells score, D-dimer, CK, and CK-MB data were also collected when the patients were diagnosed with APE. The Wells score criteria[3 (link)] were as follows: history of pulmonary embolism or deep venous thrombosis, heart rate ≥ 100 beats/minutes, history of operation or braking in the past 4 weeks, hemoptysis, active stage of malignant tumor, DVT-related symptoms, and low possibility of diagnosis other than pulmonary embolism. Each item is counted at 1 point. The normal D-dimer reference value was 0 to 0.243μg/mL. The blood and myocardial enzymes, including CK-MB, had normal reference values < 24MB.

Illustration of speckle-tracking echocardiography examination (
All examinations were performed by two technologists and 10 years experienced radiologist trained in congenital cardiac imaging. After three plane localizers through thorax revealed by steady-state free precession sequence, cine-steady state free precession sequence of two-chambers, four-chambers, and short-axis views (Protocol 1) was revealed for all patients. Each set of images was acquired with retrospective gating and 20 reconstructed cardiac phases. All the images were acquired during one or two breath-hold of 8 to 12 s duration depending on the heart rate during end-expiratory breath-hold.
A 0.2 mmol/kg of gadolinium-based contrast agent was performed if the imaging protocol was required. Contrast agent material was used for magnetic resonance angiography (MRA) for great vessels (Protocol 3), myocardial late gadolinium enhancement (Protocol 4), tissue characterization (Protocol 5), perfusion imaging (Perfusion 6), and vasculitis assessment (Protocol 8). Contrast-enhanced MRA was used to prescribe the phase-contrast imaging of the pulmonary artery, aorta. The optimal velocity encoding value of the pulmonary artery was calculated by the calculation Bernoulli equation reported gradients in the echocardiography report. Late gadolinium enhancement sequences were revealed after 10 and 15 min of injection for the assessment of myocardial disease.
Protocols 1–4 were applied for the patients with the indication of CHD. Protocols 1, 3, and 4 were applied for the patients with the indication of myocardial disease, and Protocols 1 and 7 were applied for myocardial iron assessment. Protocols 1, 5, and 6 were applied for the patients with the indication of cardiac mass. Protocols 1, 2, 3, and 4 were applied for valvular disease; protocols 1, 2, 3, 4, and 5 were applied for pericarditis; protocols 1 and 9 were applied for coronary artery assessment; and protocols 1 and 3 were applied for MRA of great vessels.
