People living with heart failure deal with major disruptions to the quality of their lives. In order to allow more time with loved ones, doctors have to be proactive in managing their patients' hearts. Luckily, for 75-year-old Lewis Brooks and his 61-year-old wife, Amy, their doctors could take charge of their care, thanks to the CardioMEMSTMHF System, an implantable pulmonary artery pressure sensor — which acts as a neighborhood watch for your heart. By keeping constant watch on their cardiac health, Lewis and Amy's doctors are able to adjust their medications in real time to keep them healthy and happy — and around to chase their grandkids. This Grandparents Day, we celebrate Lewis and Amy — and the technology that has improved the quality of their lives.
