 Cardiovascular diseases are the number one cause of death globally. Around 17.7 million people die every year from heart attacks and strokes. The IAEA supports member states like Cuba by training health staff and providing medical equipment to diagnose heart conditions. With nuclear techniques in mind, you can study a test with sensitivity and a very high specificity to detect the disease. Molecular imaging uses small amounts of radiation to give doctors a unique way to look inside the heart. Women are particularly at risk of premature death by heart disease. Women die 6% more from cardiovascular disease than men. This is a real alarming figure. They often ignore the symptoms and delay getting help. Women often have different signs and symptoms that are not very specific like fatigue, nausea, shortness of the breath and they don't associate that with cardiovascular problems so often they don't go to the physician on time. In the Institute of Cardiology and Cardiovascular Surgery in Havana, doctors are using nuclear techniques to diagnose thousands of women every year. Early diagnosis allows patients to prevent the progression of the disease and receive the appropriate medical treatment.
