Over recent years, social media use has substantially expanded not only for millennials, but across all generations. Today, it no longer remains a means for simple social networking. It has evolved into a powerful tool that can be used for career development, continued professional development and global scientific engagement. Medical professionals, have employed social media platforms to search for job opportunities, advertise meetings, participate in case discussions and network with the medical community at large. However, some caveats limit its widespread application amongst the clinical community. The purpose of this review is to discuss the utility of social media, its drawbacks and best practices for the clinicians.

The use of Twitter or other social media platforms for research can transcend current limitations in the dissemination of research and present new opportunities for research networking by connecting researchers, clinicians, policymakers, the public, and other stakeholders on a global scale. As social media influence continues to expand, it becomes increasingly important for cardiovascular researchers to employ social media strategies to increase the impact of their research work, for the ultimate goal of improved outcomes for patients living with or at risk for cardiovascular diseases. Altmetrics are novel metrics that track the attention that scholarly outputs are receiving in non-traditional sources such as in the news, blogs, and social media posts. These alternative metrics record research dissemination beyond traditional journal citation indices, while also predicting and even promoting future citations. This review outlines various methods of how social media can be used to disseminate research, guidance on how to develop a social media portfolio for consideration of academic promotion, and some best practices for promoting one’s research work.

Social Media includes different forms of online communication from Twitter, Facebook, Instagram, LinkedIn, podcasts, YouTube etc. and has advanced how information is exchanged. A notable use is engaging on Twitter at medical conferences, both for those attending the conference and the global audience who are not able to attend. It is also increasingly used as an educational tool similar to e-learning. The objective of this paper is to: 1) highlight the impact of using Twitter at cardiovascular congresses as an interactive platform for active learning as compared to passively listening to a presentation; 2) present perspectives from not only clinicians, researchers but also patients on how this information is interpreted; 3) provide recommendations for conference organizers for best practice live tweeting to share the information and knowledge beyond those in attendance; with potential for not only engagement but also educating our global community.

This review addresses the demographics of social media users and their relative health literacy. Means of overcoming health inequities via social media and the role of social media in patient education and engagement are explored. This review discusses forms of appropriate patient engagement, including the pitfalls of social media use.

Digital and social media have transformed the field of medicine. They are powerful tools that academic and non-academic physicians and healthcare providers are using to influence others, promote ideas, obtain knowledge, disseminate research and communicate with others. The history of advocacy for women in medicine and the role of social media in influencing the choice of women to choose Cardiology as a career and its role in advocacy for Women in Cardiology (WIC) have been reviewed. It has changed the way cardiologists learn, educate, and interact with each other. Social media has proven especially useful in advocating for WIC, but whether it can help improve the numbers of female doctors going into Cardiology remains to be seen. In addition to encouraging women to pursue cardiology, social media has drawn attention to key women’s rights issues affecting practicing female cardiologists.

Social Media is a rising influence in the global world of cardiovascular medicine, allowing for a dynamic approach to physician education, research dissemination and collaborative discussion. The visual nature of social media platforms, particularly Twitter, lends itself particularly well to the tremendous advances and stunning visuals of cardiac imaging. The hashtag “#cardiotwitter” provides around the clock, asynchronous, ubiquitous, free education. It allows connection among cardiac imagers across the world to share ideas and discuss contemporary issues pertaining to multimodality imaging. This review highlights the role of social media in advancing the practice of cardiac imaging and provides guidance on gaining visibility in the social media imaging community.

Traditional means to stay current in cardiology have been subscription journals and both local and national symposiums. More recently, social media has facilitated a two-way interactive sharing of information. With the use of social media platforms including Twitter, case discussions, educational quizzes and procedural demonstrations can now be shared in a conversation with unlimited parties and represents an excellent interactive educational modality for the global interventional community to share procedural techniques, share opinions and stay current on topics in interventional cardiology.

Background: Among social media (SoMe) platforms, Twitter and YouTube have gained popularity, facilitating communication between cardiovascular professionals and patients. Objective: This mixed-methods systematic review aimed to assess the source profile and content of Twitter and YouTube posts about heart failure (HF). Methods: We searched PubMed, Embase and Medline using the terms “cardiology,” “social media,” and “heart failure”. We included full-text manuscripts published between January 1, 1999, and April 14, 2019. We searched Twitter and YouTube for posts using the hashtags “#heartfailure”, “#HF”, or “#CHF” on May 15, 2019 and July 6, 2019. We performed a descriptive analysis of the data. Results: Three publications met inclusion criteria, providing 677 tweets for source profile analysis; institutions (54.8%), health professionals (26.6%), and patients (19.4%) were the most common source profiles. The publications provided 1,194 tweets for content analysis: 83.3% were on education for professionals; 33.7% were on patient empowerment; and 22.3% were on research promotion. Our search on Twitter and YouTube generated 2,252 tweets and > 400 videos, of which we analyzed 260 tweets and 260 videos. Sources included institutions (53.5% Twitter, 64.2% You- Tube), health professionals (42.3%, 28.5%), and patients (4.2%, 7.3%). Content included education for professionals (39.2% Twitter, 62.3% YouTube), patient empowerment (20.4%, 21.9%), research promotion (28.8%, 13.1%), professional advocacy (5.8%, 2.7%), and research collaboration (5.8%, 0%). Conclusion: Twitter and YouTube are platforms for knowledge translation in HF, with contributions from institutions, health professionals, and less commonly, from patients. Both focus largely on education for professionals and less commonly on patient empowerment. Twitter includes more research promotion, research collaboration, and professional advocacy than YouTube.

Purpose of Review: The purpose of the current mini-review is to describe the importance of surface ECG for the diagnosis of conduction disorder. Methods: The MEDLINE/PubMed database was used, with the keywords "ECG" and "conduction disorders": over the past 10 years. Other documents were included because of their relevance. Main Findings: Data on the anatomy and function of the cardiac electrical system have been described. Conduction disorders including sinus node dysfunction, atrioventricular blocks, intraventricular conduction disorders are exposed as to their epidemiology, etiology, presentation, anatomical site of impaired conduction of the electrical stimulus. The importance of ECG in patients with a cardiac implantable electronic device was also discussed, in addition to future perspectives. Conclusion: Surface ECG allows the diagnosis of atrioventricular and intraventricular conduction disorder and its anatomical block site most of the time, without the need for invasive tests such as electrophysiological study. Dysfunctions of cardiac implantable electronic devices can be diagnosed by ECG, as well as the prediction of response to cardiac resynchronization therapy.

Hydralazine, an arterial vasodilator, is a widely used medication for the management of hypertension and heart failure, especially for patients who cannot tolerate the use of ACEIs or ARBs. It is generally well-tolerated and has a safe profile in pregnancy. However, hydralazine can induce immune-mediated side effects, such as hydralazine-induced lupus and less commonly hydralazine- induced ANCA vasculitis. The latter most commonly affects the kidneys with or without other organ involvement. There are several cases reported in the literature of hydralazine-induced ANCA associated vasculitis (AAV) that have pulmonary manifestations, also known as hydralazine- induced pulmonary-renal syndrome (PRS), a condition with a high risk of mortality. We are reporting a case of Hydralazine-induced ANCA associated glomerulonephritis with severe diffuse alveolar hemorrhage (DAH). In addition, we will review the current literature and discuss the importance of prompt diagnosis and early management to decrease mortality and morbidity associated with this serious condition.

The purpose of the review is the analysis of clinical and experimental data on the etiology and pathogenesis of takotsubo syndrome (TS). TS is characterized by contractile dysfunction, which usually affects the apical region of the heart without obstruction of coronary artery, moderate increase in myocardial necrosis markers, prolonged QTc interval (in 50% of patients), sometimes elevation of ST segment (in 19% of patients), increase N-Terminal Pro-B-Type Natriuretic Peptide level, microvascular dysfunction, sometimes spasm of the epicardial coronary arteries (in 10% of patients), myocardial edema, and life-threatening ventricular arrhythmias (in 11% of patients). Stress cardiomyopathy is a rare disease, it is observed in 0.6 - 2.5% of patients with acute coronary syndrome. The occurrence of takotsubo syndrome is 9 times higher in women, who are aged 60-70 years old, than in men. The hospital mortality among patients with TS corresponds to 3.5% - 12%. Physical or emotional stress do not precede disease in all patients with TS. Most of patients with TS have neurological or mental illnesses. The level of catecholamines is increased in patients with TS, therefore, the occurrence of TS is associated with excessive activation of the adrenergic system. The negative inotropic effect of catecholamines is associated with the activation of β2 adrenergic receptors. An important role of the adrenergic system in the pathogenesis of TS is confirmed by studies which were performed using 125I-metaiodobenzylguanidine (125I -MIBG). TS causes edema and inflammation of the myocardium. The inflammatory response in TS is systemic. TS causes impaired coronary microcirculation and reduces coronary reserve. There is a reason to believe that an increase in blood viscosity may play an important role in the pathogenesis of microcirculatory dysfunction in patients with TS. Epicardial coronary artery spasm is not obligatory for the occurrence of TS. Cortisol, endothelin-1 and microRNAs are challengers for the role of TS triggers. A decrease in estrogen levels is a factor contributing to the onset of TS. The central nervous system appears to play an important role in the pathogenesis of TS.

Background: Biliary pericardial tamponade (BPT) is a rare form of pericardial tamponade, characterized by yellowish-greenish pericardial fluid upon pericardiocentesis. Historically, BPT reported to occur in the setting of an associated pericardiobiliary fistula. However, BPT in the absence of a detectable fistula is extremely rare. Learning objective: A biliary pericardial tamponade is a rare form of tamponade warranting a prompt workup (e.g., MRCP or HIDA scan) for a potential fistula between the biliary system and the pericardial space. A pericardio-biliary fistula can be iatrogenic or traumatic. People with a history of chest wall trauma, abdominal surgery, or chest surgery are at increased risk. The use of HIDA scanning plays a salient role in effectively surveilling for the presence of a fistula – especially when MRCP is contraindicated. Case Presentation: A 75-year-old Hispanic male presenting with dyspnea and diagnosed with cardiac tamponade is the subject of the study. Subsequent pericardiocentesis revealed biliary pericardial fluid (bilirubin of 7.6 mg/dl). The patient underwent extensive workup to identify a potential fistula between the hepatobiliary system and the pericardial space, which was non-revealing. The mechanism of bile entry into the pericardial space remains to be unidentified. Literature Review: A total of six previously published BPT were identified: all were males, with a mean age of 53.3 years (range: 31-73). Mortality was reported in two out of the six cases. The underlying etiology for pericardial tamponade varied across the cases: incidental pericardio-biliary fistula, traumatic pericardial injury, and presence of associated malignancy. - Conclusion: Biliary pericardial tamponade is a rare form of tamponade that warrants a prompt workup (e.g., Hepatobiliary Iminodiacetic Acid – HIDA scan) for an iatrogenic vs. traumatic pericardio- biliary fistula. As a first case in the literature, our case exhibits a biliary tamponade in the absence of an identifiable fistula.

Left ventricular noncompaction (LVNC) is a congenital pathology that directly affects the lining walls of myocardial tissue, causing trabeculations with blood filling in the inner wall of the heart, concomitantly with the development of a mesocardial thinning. Although LVNC was described for the first time as long ago as 1984, our understanding of the disease with regard to its genetic pattern, diagnosis, clinical presentation and treatment is still scanty. LVNC can present as an isolated condition or associated with congenital heart disease, genetic syndromes or neuromuscular disease. This suggests that LVNC is not a distinct form of cardiomyopathy, but rather a morphological expression of different diseases. Recognition of the disease is of fundamental importance because its clinical manifestations are variable, ranging from the absence of any symptom to congestive heart failure, lethal arrhythmias and thromboembolic events. The study of this disease has emphasized its genetic aspects, as it may be of sporadic origin or hereditary, in which case it most commonly has an autosomal dominant inheritance or one linked to the X chromosome. Echocardiography is the gold standard for diagnosis, and magnetic resonance imaging may refine the identification of the disease, especially in those patients with non-conclusive echocardiography. This article sets out to review the main characteristics of LVNC and present updates, especially in the genetic pattern, diagnosis and treatment of the disease.

Atrial fibrillation is the most common supraventricular arrhythmia affecting an increasing proportion of the population in which mainstream therapy, i.e. catheter ablation, provides freedom from arrhythmia in only a limited number of patients. Understanding the mechanism is key in order to find more effective therapies and to improve patient selection. In this review, the structural and electrophysiological changes of the atrial musculature that constitute atrial remodeling in atrial fibrillaton and how risk factors and markers of disease progression can predict catheter ablation outcome will be discussed in detail.
