This book gathers the latest research from around the world on hypertension and stroke. While it is widely known how raised heart rate adversely affects ischaemic heart disease and congestive heart failure, it has not been clearly shown how low heart rate increases tendency to stroke. Thus the influence of heart rate on development of stroke is examined in this book. The etiology of paediatric stroke, a potentially devastating condition, is also discussed, since it is an important condition that often remains unknown in a considerable number of patients. Furthermore, arterial hypertension and cardiovascular complications in patients with glomerular kidney disease are also explored in this book. The progress that has been made towards identifying the genetics of risk factors in polygenic and multifactorial intracerebral hemorrhage (ICH) is presented and data regarding monogenic conditions associated with ICH is summarised. Other chapters in this book include the examination of the association between blood pressure (BP) and bone mineral content (BMC) in paediatrics; arterial hypertension as one of the main clinical symptoms of aortic coarctation in children, and a review of ambulatory blood pressure monitoring (ABPM) as a non-invasive method of blood pressure assessment, which is considered to be a very useful tool in the diagnosis of arterial hypertension in adults, teenagers and children.
