Preservation of the heart in ancient Egyptian mummies: A computed tomography investigation with focus on the myocardium

Stephanie Panzer, Alice Paladin, Stephanie Zesch, Wilfried Rosendahl, more

The ancient Egyptians considered the heart to be the most important organ. The belief that the heart remained in the body is widespread in the archeological and paleopathological literature. The purpose of this study was to perform an overview of the preserved intrathoracic structures and thoracic and abdominal cavity filling, and to determine the prevalence and computed tomography (CT) characteristics...

Left main and triple vessel dissection 2 months postpartum

Negeen Shahandeh, Michael I. Miyamoto, Jonathan Tobis

Catheterization and Cardiovascular Interventions > 93 > 7 > 1290 - 1294

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome. The majority of cases reported in the literature involve a single vessel; multivessel and left main (LM) coronary artery involvement is rare. We present a case of triple vessel and LM SCAD in a postpartum patient and review the literature regarding percutaneous coronary intervention in the setting of SCAD.

How B-Type Natriuretic Peptide (BNP) and Body Weight Changes Vary in Heart Failure With Preserved Ejection Fraction Compared With Reduced Ejection Fraction: Secondary Results of the HABIT (HF Assessment With BNP in the Home) Trial

Alan S. Maisel, Kevin S. Shah, Denise Barnard, Brian Jaski, more

Journal of Cardiac Failure > 2016 > 22 > 4 > 283-293

Heart failure is a common cause of hospitalization and can be divided into types with preserved and reduced ejection fraction (HFpEF and HFrEF, respectively). In this subanalysis of the HABIT (Heart Failure Assessment With BNP in the Home) trial, we examined the differences between home B-type natriuretic peptide (BNP) testing and weight monitoring in patients with HFpEF and with HFrEF before decompensation...

Randall C. Thompson, Adel H. Allam, Albert Zink, L. Samuel Wann, more

Global Heart > 2014 > 9 > 2 > 187-196

Although atherosclerosis is widely thought to be a disease of modernity, computed tomographic evidence of atherosclerosis has been found in the bodies of a large number of mummies. This article reviews the findings of atherosclerotic calcifications in the remains of ancient people—humans who lived across a very wide span of human history and over most of the inhabited globe. These people had a wide...

Atherosclerosis in Ancient Humans, Accelerated Aging Syndromes and Normal Aging

Michael I. Miyamoto, Karima Djabali, Leslie B. Gordon

Global Heart > 2014 > 9 > 2 > 211-218

Imaging studies of ancient human mummies have demonstrated the presence of vascular calcification that is consistent with the presence of atherosclerosis. These findings have stimulated interest in the underlying biological processes that might impart to humans an inherent predisposition to the development of atherosclerosis. Clues to these processes may possibly be found in accelerated aging syndromes,...

Funerary Artifacts, Social Status, and Atherosclerosis in Ancient Peruvian Mummy Bundles

M. Linda Sutherland, Samantha L. Cox, Guido P. Lombardi, Lucia Watson, more

Global Heart > 2014 > 9 > 2 > 219-228

Evidence of atherosclerotic plaques in ancient populations has led to the reconsideration of risk factors for heart disease and of the common belief that it is a disease of modern times.Fifty-one wrapped mummy bundles excavated from the sites of Huallamarca, Pedreros, and Rinconada La Molina from the Puruchuco Museum collection in Lima, Peru, were scanned using computed tomography to investigate the...

Why Did Ancient People Have Atherosclerosis?

Gregory S. Thomas, L. Samuel Wann, Adel H. Allam, Randall C. Thompson, more

Global Heart > 2014 > 9 > 2 > 229-237

Computed tomographic findings of atherosclerosis in the ancient cultures of Egypt, Peru, the American Southwest and the Aleutian Islands challenge our understanding of the fundamental causes of atherosclerosis. Could these findings be true? Is so, what traditional risk factors might be present in these cultures that could explain this apparent paradox? The recent computed tomographic findings are...

Genomic Correlates of Atherosclerosis in Ancient Humans

Albert Zink, L. Samuel Wann, Randall C. Thompson, Andreas Keller, more

Global Heart > 2014 > 9 > 2 > 203-209

Paleogenetics offers a unique opportunity to study human evolution, population dynamics, and disease evolution in situ. Although histologic and computed x-ray tomographic investigations of ancient mummies have clearly shown that atherosclerosis has been present in humans for more than 5,000 years, limited data are available on the presence of genetic predisposition for cardiovascular disease in ancient...

Atherosclerosis in Ancient and Modern Egyptians

Adel H. Allam, Mohamed A. Mandour Ali, L. Samuel Wann, Randall C. Thompson, more

Global Heart > 2014 > 9 > 2 > 197-202

Although atherosclerosis is usually thought of as a disease of modernity, the Horus Team has previously reported atherosclerotic vascular calcifications on computed tomographic (CT) scans in ancient Egyptians.The purpose of this study was to compare patterns and demographic characteristics of this disease among Egyptians from ancient and modern eras.We compared the presence and extent of vascular...

Atherosclerotic cardiovascular disease in Egyptian women: 1570 BCE–2011 CE

Alia Abdelfattah, Adel H. Allam, Samuel Wann, Randall C. Thompson, more

International Journal of Cardiology > 2013 > 167 > 2 > 570-574

Atherosclerotic cardiovascular disease is often thought of as a disease of modernity, a disease affecting primarily men and a disease primarily affecting members of affluent Western societies.We reviewed CT scans for evidence of vascular calcification as a manifestation of atherosclerosis in ancient Egyptian female mummies and compared the results to clinical features of contemporary Egyptian women,...

Primary Results of the HABIT Trial (Heart Failure Assessment With BNP in the Home)

Alan Maisel, Denise Barnard, Brian Jaski, Geir Frivold, more

Journal of the American College of Cardiology > 2013 > 61 > 16 > 1726-1735

This study was a multicenter, single-arm, double-blinded observational prospective clinical trial designed to monitor daily concentrations of B-type natriuretic peptide (BNP) and to determine how these concentrations correlate with acute clinical heart failure decompensation (ADHF) and related adverse clinical outcomes in at-risk HF patients.Although BNP at discharge is predictive of 30-day outcomes,...

Atherosclerosis across 4000 years of human history: the Horus study of four ancient populations

Randall C Thompson, Adel H Allam, Guido P Lombardi, L Samuel Wann, more

The Lancet > 2013 > 381 > 9873 > 1211-1222

Atherosclerosis is thought to be a disease of modern human beings and related to contemporary lifestyles. However, its prevalence before the modern era is unknown. We aimed to evaluate preindustrial populations for atherosclerosis. We obtained whole body CT scans of 137 mummies from four different geographical regions or populations spanning more than 4000 years. Individuals from ancient Egypt,...
