HRH Grand Duke Henri of Luxembourg was sent to the Centre Hospitalier de Luxembourg today after feeling “unwell”. He reportedly suffered a cardiac arrest and had an emergency angioplasty. The latest official news from the Palais is that the Grand Duke's condition is "not worrying.” He remains in the hospital, most likely for observation as the procedure was deemed a success. Both of the Grand Duke’s uncles King Baudouin of Belgium and Prince Charles of Luxembourg died young of heart problems, so Henri’s family has reason to be cautious. After having a similar balloon angioplasty procedure, HRH will most likely need to stay in the hospital for 2-3 days. After that he could need a significant period of rest, up to or even exceeding a month. It is possible, depending on what caused the issue that the Grand Duke had, he could need to be on medication for the foreseeable future. HRH the Grand Duke had been in reportedly good health, he is 55 years old.
