Machine Intelligence in Cardiovascular Medicine

The computer science technology trend called artificial intelligence (AI) is not new. Both machine learning and deep learning AI applications have recently begun to impact cardiovascular medicine. Scientists working in the AI domain have long recognized the importance of data quality and provenance to AI algorithm efficiency and accuracy. A diverse array of cardiovascular raw data sources of variable quality—electronic medical records, radiological picture archiving and communication systems, laboratory results, omics, etc.—are available to train AI algorithms for predictive modeling of clinical outcomes (in-hospital mortality, acute coronary syndrome risk stratification, etc.), accelerated image interpretation (edge detection, tissue characterization, etc.) and enhanced phenotyping of heterogeneous conditions (heart failure with preserved ejection fraction, hypertension, etc.). A number of software as medical device narrow AI products for cardiac arrhythmia characterization and advanced image deconvolution are now Food and Drug Administration approved, and many others are in the pipeline. Present and future health professionals using AI-infused analytics and wearable devices have 3 critical roles to play in their informed development and ethical application in practice: (1) medical domain experts providing clinical context to computer and data scientists, (2) data stewards assuring the quality, relevance and provenance of data inputs, and (3) real-time and post-h...

Abstract Corona Virus Disease 2019 (COVID-19) pandemic has impacted health and economy worldwide on an unprecedented scale. Patients have diverse clinical outcomes, but those with pre-existing cardiovascular (CV) disease, hypertension, and related conditions incur disproportionately worse outcome. The high infectivity of the SARS-CoV-2 virus is in part related to new mutations in the receptor binding domain, and acquisition of a furin cleavage site in the S spike protein. The continued viral shedding in the asymptomatic and pre-symptomatic individuals enhances its community transmission. The virus uses the ACE2 re...

Abstract Atrial fibrillation is the most common cardiac arrhythmia in western society affecting more than 35 million individuals worldwide annually. It is a common postoperative complication and may also occur spontaneously during general and local anesthesia administration. Aging, diabetes mellitus, hypertension, and cardiovascular diseases including cardiomyopathies, congenital cardiac anomalies, heart failure, myocardial ischemia, pericarditis, previous cardiac surgery, vascular disease, and valvular heart disease are some correlated factors. Beyond age, increased incidence of atrial fibrillation has been corre...

We present an unusual case of indapamide-induced hyponatremia and hypokalemia complicated by cardiac arrhythmia. The adverse drug reaction was reversible and non-life-threatening, but this case serves as a reminder that careful evaluation and constant monitoring are necessary when prescribing diuretics.

The objective of this study was to review the current status of drug-induced hypomagnesemia and its adverse effects on cardiovascular disease (CVD) and hypertension. Since magnesium is a potent vasodilator, which modulates vasomotor tone, peripheral blood flow and hypertension, its deficiency could have significant cardiovascular and blood pressure (BP) effects.Areas covered: Studies have shown that several factors can contribute to magnesium deficiency including age, diet, disease, and certain drugs such as diuretics and proton pump inhibitors (PPIs). For an updated perspective of drug-induced hypomagnesemia, a Medline se...

Campbell, CA-based VivaLNK has received Class IIa medical device CE mark for its multi-vital medical wearable sensor and software development kit.  VivaLNK is a Qmed-qualified supplier.   At 7.5 grams, the reusable patch is the smallest of its kind, VivaLNK said. The company also noted that the reusability factor can increase the economic value of using the patch 10-times or more than single-use devices. Also, VivaLNK said the combination of a wearable sensor and an associated software development kit enables any application developer to build medica...

AbstractPurpose of ReviewTo review the clinical evidence for a relationship between obstructive sleep apnea and hypertension, arrhythmias, coronary artery disease, and congestive heart failure.Recent FindingsCurrent data show that obstructive sleep apnea is a risk for cardiovascular disease. Studies have linked untreated moderate to severe obstructive sleep apnea to hypertension, cardiac arrhythmias, coronary artery disease, and congestive heart failure. However, uncertainty regarding benefits of treatment of obstructive sleep apnea to reduce the risk of cardiovascular disease still exists. The issue of poor compliance has...

Abstract Ambient and household air pollution is a major health problem, contributing globally and annually to approximately 7 millions of all-cause avoidable deaths, shortening of life expectancy and significant direct and indirect costs for the community. Air pollution is a complex mixture of gaseous and particulate materials, that vary depending on their source and physicochemical features. Each material has detrimental effects on human health, but a number of experimental and clinical studies have shown a strong impact for fine particulate matter (PM2.5). In particular, there is more and more evidence that PM2....

Hypertension is the most common cardiovascular risk factor and underlies heart failure, coronary artery disease, stroke, and chronic kidney disease. Hypertensive heart disease can manifest as cardiac arrhythmias. Supraventricular and ventricular arrhythmias may occur in the hypertensive patients. Atrial fibrillation and hypertension contribute to an increased risk of stroke. Some antihypertensive drugs predispose to electrolyte abnormalities, which may result in atrial and ventricular arrhythmias. A multipronged strategy involving appropriate screening, aggressive lifestyle modifications, and optimal pharmacotherapy can re...
