Preface
"Anginapectoriswithnonnal coronary arteriograms" isa common entity which has
puzzledcardiologistsalmostsincetheadventofcoronaryarteriography. Asa matter
of fact, chest pain in the absence ofatheromatous coronary disease represented a
diagnosticproblemevenbeforethearteriographyera. "Pseudo-angina" (chestpainin
theabsenceofcoronaryarteriosclerosis) wasdescribedbyWilliamOslerinhisbook
"ThePrinciplesandPracticeofMedicine",as the"chiefdifficulty" in thediagnosisof
"trueangina". Pseudo-anginawasa"commonaffectionin women" butcouldalsobe
foundin"neurasthenicmen".
Despitemajoradvances in the understandingofthepathophysiologyofanginain
recent years and a multitude of studies on the subject, the cause and mechanisms
underlying the syndromeofangina with nonnalcoronary arteries remain unknown.
Indeed, results of investigations are controversial and speculation still prevails
regarding thenatureofthesocalled"SyndromeX".
Why therefore write a book about "Syndrome X"; an ill-defined entity which
offerssomanyobscureaspects; asyndromewhosedefinition is far from precise? It
is because of its controversial nature, the lack of agreement between researchers
regarding the precise definition of the syndrome, and the sense of frustration that
"Syndrome X" imposes on both patient and physician, that I thought that a
monograph on the subjectwas necessary. Iwas hauntedby the ideaofproducing a
book which would reflect not only current, objective, cardiological knowledge on
syndrome X, but also the views of specialists in other medical fields who also
"battle" with theproblemofchestpainofunexplainedorigin. Irealized thattheidea
of a multidisciplinary monograph on "Syndrome X" was not only desirable, but
possible, after our "Workshop on Angina with Normal Coronary Arteries" in June
1992at St. George's Hospital inLondon. At this meeting, which gathered together
many of the contributing authors of this book, we had fruitful discussions on the
heterogeneityandpossiblenatureofSyndromeX. Theneedtoworkincollaboration
towardsabetterunderstandingoftheproblembecameobvious. Itwas then apparent
to me that there was "light at the end of the tunnel" insofar as investigators and
x
clinicians witha genuine interestin syndrome X made an effortto carefully dissect
thediversecomponentsofthisentity.
Thecontributing authors haveacceptedthechallengeand "teamed up" undermy
editorship,forwhich Iamextremelygratefulandunderstandablyproud. Weaimedat
providingacomprehensive viewofthe problem ofSyndromeX. The authors, who
are notonly top scientistsbutalso sagaciousclinicians, havegenerouslycontributed
their knowledgeand personal views to this monograph. I trust that the readers will
enjoy,asmuchIdid, going through every pageofthebookto discoverthemultitude
ofestablishedconceptsandnew ideassocarefully"seeded"byauthoritiesinthefield.
Almostevery importantaspectofsyndromeX hasbeen tackledin the bookand the
reader will be exposed not only to the cardiologists' opinion, but also to the
authoritative views of the gastroenterologists, gynaecologists and psychiatrists,
extremely well represented in this monograph. Our book deals with the
"cardiologistssyndromeX" andnot the metabolicentity recently termed "syndrome
X". Thepossibleconnection between the two "syndromeX", however, isdiscussed
in the book.
This bookdoes notattempt to be "the last word" on SyndromeX, an impossible
taskwhendealingwithsucharapidlyevolvingfield. Weareaware thatperhapsonly
some ofthe new challenging concepts and hypotheses discussed in the monograph
may be confirmed in the future (but at present we do not know which!) whereas
others will have tobeabandoned when supersededby new concepts. Ouraim is to
contribute to the understanding of Syndrome X and we will feel rewarded if this
monograph serves the double purpose of helping clinicians to manage their
SyndromeXpatientsbetterandinvestigatorstoopennewavenuesforresearch.

I am greatly indebted to the authors, who generously contributed authoritative
chapters to the monograph; and to Allison Baker, my Research Assistant, who
workedextremelyhardindiverseaspectsoftheeditorialprocess. Hercontributionto

Aneducationalgrantfrom BayerUKmadethisbookpossible. Iacknowledgethe
kindnessandgenerosityofDrGarryMacdonaldandRobinBhattacheIjeewhodecided
to support our monograph taking into account its scientific value rather than its
negligible"marketing" potential.
Ithankmy wife, Marta,andmychildrenJuan Pablo,DiegoandMarlaCeciliafor
their loveand patienceandalso for encouragingme to geton with this work. Iam
also grateful to my father, M. Kaski, MD, who taught me that Medicine is about
