Heart arrhythmia resents a significant burden to patients, ranging from the impact of debilitating symptoms on daily life to the increased risk of stroke and/or death. If not treated efficiently, heart arrhythmia can lead to sudden cardiac arrest, which is a public health problem and accounts for 50% of cardiovascular deaths and 20% of all natural deaths in Western societies. This problem is expected to rise further as the population ages, since sudden cardiac arrest mostly strikes individuals older than 60 years. The population aging worldwide will result in increasing numbers of elderly patients, among whom heart diseases are the leading cause of death. Today, almost a billion people are over 65. EBAMed’s activities represent a unique opportunity to efficiently treat arrhythmia and reduce mortality from heart disease in a safe, non-invasive and effective way. Additionally, proton therapy as a treatment option continues to expand as new facilities continue to be built. The number of proton therapy centers in the EU is steadily increasing and will reach 52 facilities across Europe by 2020.
