Nice review of the media coverage and its problems related to @Apple watch with added clarity about data @US_FDA used to approve from @thejoyvictory at @HealthNewsRevu.

Lots of headlines @escardio re CT-FFR. 1 of most prominent is ADVANCE multicenter registry from @manesh_patelMD & colleagues using @HeartFlow. I'd like to dissect this a bit to see how excitement in a field combined with lots of industry funding can blind us to basic problems. Team worked across 38 international sites over >2 years to collect data from N=5083 patients w/ “symptoms concerning for CAD”. They had primary endpoint of change in management plan from coronary CTA. That happened in 67% of patients. Most impressive.

More hype around AI, mHealth, wearables. @AliveCor devices can use #AI to find LQTS:

prnewswire.com/news-releases/… From the press release:

AUC 0.83, specificity 81%, sensitivity 73%, accuracy 79%

Prevalence of LQTS 160,000 out of US population of 325.7 million (0.049%)
