Modern science detects disease in 400-year-old embalmed hearts

By Will Dunham WASHINGTON (Reuters) - In the ruins of a medieval convent in the French city of Rennes, archaeologists discovered five heart-shaped urns made of lead, each containing an embalmed human heart. It turns out three of them bore tell-tale signs of a heart disease very common today. "Every heart was different and revealed its share of surprises," anthropologist Rozenn Colleter of the French National Institute for Preventive Archaeological Research said on Wednesday. http://dlvr.it/CwsxDk

3 to 5 Cups of Coffee a Day May Lower Risk of Heart Attacks

Good news for people who drink coffee every day: Consuming a moderate amount of coffee could lower the risk of clogged arteries that can lead to a heart attack, a new study finds. The study of healthy young adults in Korea found that, compared with people who didn't drink coffee, those who drank three to five cups of java per day had a lower risk of having calcium deposits in their coronary arteries, which is an indicator of heart disease. The study participants who drank three to four cups had the lowest risk of developing clogged arteries seen in the study, said Dr. Eliseo Guallar, an epidemiologist at Johns Hopkins University Bloomberg School of Public Health in Baltimore, Maryland, and co-author of the study published today (March 2) in the journal Heart. "But the risk went down with just one cup per day," compared with the risk of people who drank no coffee, Guallar added. http://dlvr.it/8pSF7f

Ascending Aorta (Coronary ostia):

Right Coronay Artery (RCA)

Left Coronary Artery (LCA)

Right Coronary Artery:

Conus branch

SA nodal branch

Right Marginal art: RV

AV nodal branch

Posterior Interventricular -or Posterior Descending- Art (PIV or PDA): R&L Ventricles, posterior 1/3 of IV septum

Left Coronary Artery (LCA)

Circumflex art (CxA): LA & LV posterior wall, LV interventricular wall

Left Anterior Descending -or Anterior Interventricular- Artery (LAD or AIV): RV, >LV,  anterior 2/3 of interventricular septum, bundle of His, apex

Coronary Sinus

Final endpoint of coronary flow

Continuous with the right atrium

Receives the great cardiac vein

Becomes dilated in chronic pulmonary hypertension 

Blood in the coronary sinus has the lowest oxygen content in the body, with oxygen saturation levels of 30% 

Coronary Arterial System Dominance: Which artery gives rise to Posterior Descendant -or Posterior Interventricular- Art?

Right Dominance (80%) = RCA gives rise to PDA

Left Dominance (20%) = CFX artery gives rise to PDA
