What connects these topics?
The heart pumps blood, blood vessels carry it through the body, and the smallest vessels allow substances to move between blood and tissues. Cardiovascular health needs to be considered in the context of overall risk: alongside blood pressure and blood lipids, factors such as blood glucose, smoking, physical activity and nutrition matter.
Each article explains a different part of the picture. A blood-drop image or a single measurement does not, by itself, establish a diagnosis.
Frequently asked questions
Where should I start?
For an overview, start with article 03 about the heart and blood vessels. If you have a specific question, choose the relevant article from the menu. You can also read each article individually.
Can a blood-drop image identify a disease?
No. A blood-drop image alone does not replace validated laboratory testing or professional diagnosis.
What matters for heart and blood vessel health?
Assessment depends on your overall health. Blood pressure, blood lipids, blood glucose, smoking and other individual risk factors are commonly considered. A healthcare professional interprets the findings.
