Contributions of treatment and lifestyle to declining CVD mortality: why have CVD mortality rates declined so much since the 1960s?

Developed countries have enjoyed substantial falls in cardiovascular disease (CVD) mortality. However, low and middle income countries are drowning in a rising tide of CVD and other non-communicable diseases. Current and future trends in CVD mortality will therefore require increasing attention in the 21st century. The success of clinical cardiology in providing evidence-based cost-effective treatments should be celebrated. However, the growing understanding of CVD mortality trends highlights the crucial role of tobacco, diet, alcohol and inactivity as key drivers. Pro-active public health approaches focused on 'upstream' population-wide policies are increasingly recognised as being potentially powerful, rapid, equitable and cost-saving. However, the future political challenges could be substantial.
