Panic disorder in patients with angiographically normal coronary arteries.
Several lines of investigation strongly support the notion that panic disorder afflicts at least one third of patients with angiographically normal coronary arteries and unexplained chest pain. Panic disorder is a common problem, affecting 1-2% of the U.S. population. Current research suggests an etiology that is both psychophysiologic and cognitive. The locus ceruleus and cortico-releasing factor are implicated in the biological circuit associated with panic attacks, while psychological research indicates that catastrophic thinking, phobic responses to somatic sensations, and repressed anger, grief, and traumatic events play a part in triggering attacks. Treatment consists of pharmacologic interventions, including antidepressants and benzodiazepines, as well as psychotherapeutic work focusing on catastrophic thinking and repressed anger, grief responses, and other traumatic experiences.

Further evaluation of the MMPI Pan scale in psychiatric and medical patients.
The efficiency of a recently developed MMPI scale (Pan) to identify panic disorder was assessed in samples of both psychiatric and medical patients. Particular attention was paid to base rates and cutting scores. The Pan scale was found to have utility in rule-out clinical decision making. Suggestions for further validation studies are discussed.

Panic disorder in the families of patients with normal coronary arteries and non-fear panic disorder.
Patients with non-fear panic disorder (NFPD) meet DSM-III-R criteria for panic disorder, but do not report subjective fear or anxiety. Although apparently common in medical settings, this controversial group is in need of further diagnostic validation. This study assessed family history of panic disorder in patients with chest pain and normal coronary arteries (CP/NCA) and either NFPD, panic disorder with fear, or no panic. It was hypothesized that the two panic disorder groups would have similar, elevated rates of panic disorder in their first-degree relatives, compared to patients without panic. The results support the hypothesis; about 17% of the first-degree relatives of both NFPD and panic disorder patients were diagnosable with panic disorder according to proband interviews, whereas only 4.6% of the first-degree relatives of patients without panic were so diagnosable. These results support the diagnostic validity of NFPD in CP/NCA patients, because such patients had a family history of panic disorder similar to patients with a more classical panic disorder presentation. The lack of fear symptoms and behavior in NFPD may cause panic disorder to be overlooked as a potential cause of somatic symptoms in patients with no medical explanation for their condition.

Panic disorder history in the families of patients with angiographically normal coronary arteries.
OBJECTIVE: The authors evaluated the diagnostic validity of an interview-based panic disorder diagnosis in cardiology chest pain patients with angiographically normal coronary arteries. METHOD: Patient probands with normal coronary arteries (N = 65) were first contracted immediately after their normal angiogram and were given a structured diagnostic interview. On the basis of the results of the interview, probands were grouped as having panic disorder (N = 19), panic attacks that did not meet frequency criteria for panic disorder (N = 17), or no panic (N = 29). At a later time, patient probands were recontacted and given a structured family history interview that inquired about psychopathology in their first-degree biological relatives (N = 544). RESULTS: As predicted, panic disorder was significantly more prevalent among the first-degree relatives of probands with normal coronary arteries diagnosed with panic disorder or panic attacks than among the family members of probands with normal coronary arteries without panic (17.4% versus 15.7% versus 4.0%). Family members of probands with panic attacks were significantly more likely to be diagnosed with major depression than were the family members of probands with no panic; however, differences did not reach significance for family members of the panic disorder proband group. Groups did not differ significantly in familial alcoholism. CONCLUSIONS: These data support the construct validity of an interview-based panic disorder diagnosis among patients with chest pain and normal coronary arteries and suggest that these patients could benefit from treatment for panic disorder.

Response to 35% CO2 in patients with chest pain and angiographically normal coronary arteries.
OBJECTIVES: Several interview studies have suggested that panic disorder (PD) exists in patients with angiographically normal coronary arteries (NCA). Interview studies require corroboration by other studies in order to validate them. The purpose of this study is to test whether response to the inhalation of 35% CO2 reliably discriminates between PD and non-panic disorder patients in this population. METHOD: Three groups were studied: six with NCA and PD, five with NCA and no PD, and ten in the control group. All subjects breathed room air, then 35% CO2 in a single-blind fashion. Each completed the Acute Panic Inventory (API) before and during the procedure. RESULTS: The NCA-panic group scored significantly higher than the other two groups on the Acute Panic Inventory from baseline to post-inhalation. CONCLUSION: Despite several methodological limitations including a relatively small number people in each cells, 35% CO2 was shown to trigger more intense responses in panic patients, thus helping to validate the interview findings.

Follow-up status of patients with angiographically normal coronary arteries and panic disorder.
Cardiology patients with normal coronary angiography demonstrate continuing and substantial social, health, and work disability. We hypothesized that the diagnosis of panic disorder would mark those for whom continuing disability is most likely. We interviewed 72 such patients at the time of their normal angiogram, and then again an average of 38 months later. Those with panic disorder (n = 36) demonstrated significantly more disability at follow-up than did the other study patients. We conclude that those patients with normal angiograms who have panic disorder are more disabled than those who do not have panic disorder. Panic disorder in psychiatric samples has been shown to be highly treatable. Therefore, early identification and treatment of panic disorder in this group is likely to minimize the suffering associated with this condition.

Mitral valve prolapse, panic disorder, and chest pain.
Mitral valve prolapse is a common cardiac disorder that can readily be diagnosed by characteristic auscultatory and echocardiographic criteria. Although many diseases have been associated with mitral valve prolapse, most affected individuals have the primary form of the disorder. Mitral valve prolapse is an inherited condition commonly associated with myxomatous degeneration of the mitral valve and its support structures. Complications of mitral valve prolapse, including cardiac arrhythmias, sudden death, infective endocarditis, severe mitral regurgitation (with or without chordae tendineae rupture), and cerebral ischemic events, occur infrequently considering the wide prevalence of the disorder. Panic disorder is a specific type of anxiety disorder characterized by at least three panic attacks within a 3-week period or one panic attack followed by fear of subsequent panic attacks for at least 1 month. It too is a common condition with a prevalence and age and gender distribution similar to that of mitral valve prolapse. Panic disorder and mitral valve prolapse share many nonspecific symptoms, including chest pain or discomfort, palpitations, dyspnea, effort intolerance, and pre-syncope. Chest pain is the symptom in both conditions that most commonly brings the patient to medical attention. The clinical description of chest pain in patients with mitral valve prolapse is highly variable, possibly reflecting multiple etiologies. Chest pain in panic disorder is usually characterized as atypical angina pectoris and as such bears resemblance to the chest pain commonly described by patients with mitral valve prolapse. Multiple investigative attempts to elucidate the mechanism of chest pain in both conditions have failed to identify a unifying cause. Review of the literature leaves little doubt that mitral valve prolapse and panic disorder frequently co-occur. Given the similarities in their symptomatology, a high rate of co-occurrence is, in fact, entirely predictable. There is, however, no convincing evidence of a cause-effect relationship between the two disorders, nor has a single pathophysiologic or biochemical mechanism been identified that unites these two common conditions. Until specific biologic markers for these disorders are identified, it may be impossible to do so. The lack of a proven cause-and-effect relationship between mitral valve prolapse and panic disorder and the absence of a unifying mechanism do not diminish the clinical significance of the high rate of co-occurrence between the two conditions. Primary care physicians and cardiologists frequently encounter patients with mitral valve prolapse and nonspecific symptoms with no discernible objective cause who fail to respond to beta-blockade. Panic disorder should be considered as a possible explanation for symptoms in such patients.(ABSTRACT TRUNCATED AT 400 WORDS)

Validating studies for panic disorder in patients with angiographically normal coronary arteries.
This article describes validating studies for diagnosing panic disorder in some patients with angiographically normal coronary arteries (NCA) and chest pain. Psychiatric interviews of 94 such patients showed that 34% met the diagnostic criteria for panic disorder. Further studies showed that NCA patients with panic disorder were more disabled at 3.5-year follow-up, had more relatives with panic disorder, were more likely to suffer from major depression, and were more likely to respond to 35% CO2 challenge with panic symptoms. Because panic disorder is highly disabling but responds well to psychological and pharmacologic treatments, screening NCA patients in the cardiology population for this disorder is recommended.

Nonfearful panic disorder in neurology patients validated by lactate challenge.
OBJECTIVE: Nonfearful panic disorder meets the DSM-III-R criteria for panic disorder but is not associated with subjective fear and anxiety. The authors determined its prevalence in a group of neurology patients and assessed its diagnostic validity as a panic disorder subtype by evaluating the response of the patients with nonfearful panic disorder to sodium lactate and antipanic pharmacotherapy. METHOD: The subjects were all neurology patients referred over 1 year to a university hospital's psychiatric consultation service because of negative medical workups for their symptoms (N = 48). Patients who met the DSM-III-R criteria for panic disorder but did not report subjective anxiety or fear during panic episodes were diagnosed as having nonfearful panic disorder. Afterward, each of those patients received a sodium lactate infusion and, 5 hours later, a sodium chloride infusion. They were then treated with antipanic medication and followed for at least 6 months. RESULTS: Of the 48 neurology patients referred for psychiatric evaluation, 11 (23%) met the criteria for panic disorder, and all 11 met the criteria for nonfearful panic disorder. All 11 responded positively to lactate but not to placebo, and they each experienced an at least 75% reduction in symptoms during the 6-month follow-up period. Detailed case reports of three of these patients are presented. CONCLUSIONS: These findings support the construct and predictive diagnostic validity of nonfearful panic disorder as a subtype of panic disorder and suggest that a lack of attention to this group leads to both the underestimation of the prevalence of panic disorder and to the withholding of potentially successful treatments for this group.

Late onset panic disorder: evidence from a study of patients with chest pain and normal cardiac evaluations.
In the context of administering psychiatric diagnostic interviews to cardiology patients with chest pain and no evidence of coronary artery disease, the authors found twenty-seven patients over the age of sixty-five, nine (33%) of whom fit panic disorder criteria. Their mean age of onset was sixty-two (SD = 23 years). Only two patients reported onset of panic disorder earlier than age sixty-two. All nine were widows while the comparison group of non-panic subjects over age sixty-five included only seven of eighteen (40%) who were widows. These findings suggest panic disorder may be prevalent in older patients with chest pain and no evidence of coronary artery disease and that panic disorder may begin later in life.

Panic attacks without fear: an overview.
'Non-fearful panic disorder' (NFPD) is a condition that meets DSM III-R criteria for panic disorder but lacks a report of subjective fear or anxiety. Presenting the first comprehensive overview of this issue, the authors describe studies investigating a wide range of apparently overlapping phenomena including NFPD, 'somatically expressed panic', 'non-cognitive panic', 'alexithymic panic', 'non-clinical panic', and 'masked anxiety'. The review shows that such conditions account for from 20 to 40% of the panic disorder found in various medical populations, and that this group resembles conventional panic disorder in cross-sectional comparisons. We emphasize that a 'triple-response' model of anxiety is consistent with our conclusion that NFPD should be conceptualized as a panic disorder subtype. Finally, we discuss unresolved issues regarding the construct and predictive diagnostic validity of NFPD.

Panic disorder without fear in patients with angiographically normal coronary arteries.
By DSM-III-R criteria, patients may be diagnosed as having panic disorder without reporting the experience of intense fear. However, if such patients do not report subjective fear, they may be less likely to receive a panic diagnosis. The authors studied 32 subjects with angiographically normal coronary arteries who fit panic disorder criteria. A total of 13 (41%) reported no fear during their last major attack. These subjects were contrasted with those who did report fear. Few differences were found in group demographic data or responses to self-report questionnaires. We conclude that there appear to be few differences between the nonfear panic disorder subjects and those who do report fear. This conclusion awaits further support using challenge tests, medication trials, biological indices, alexithymia inventories, and family studies. The recognition of the existence of this subtype is likely to increase the number of patients receiving the panic disorder diagnosis in cardiology settings, in psychiatric settings, and in research projects using structured clinical interviews.

The relation between alcohol problems and the anxiety disorders.
The idea that people suffering from anxiety have a proclivity to consume alcohol to relieve their symptoms is supported by reports showing high comorbidity rates of alcohol and anxiety problems. The authors reviewed relevant epidemiologic surveys, family studies, and field studies and conclude that the relationship between alcohol problems and anxiety appears to be variable among the anxiety disorders. In agoraphobia and social phobia, alcohol problems appear more likely to follow from attempts at self-medication of anxiety symptoms, but panic disorder and generalized anxiety disorder may be more likely to follow from pathological alcohol consumption. Simple phobia does not appear to be related to alcohol problems in any meaningful way.

Major depression and agoraphobia in patients with angiographically normal coronary arteries and panic disorder.
Patients with panic disorder and/or agoraphobia appearing in psychiatric settings report rates for lifetime major depression between 24% and 91%. Between 40% and 90% of patients with panic disorder in psychiatric populations report concomitant agoraphobia. A recent study of panic disorder subjects appearing in an outpatient cardiology clinic confirmed the strong link between panic and depression but found only a weak association between panic disorder and agoraphobia. In order to test the reliability of these outpatient cardiology findings, the authors studied major depression and agoraphobia in patients with angiographically normal coronary arteries and panic disorder. Twelve of the 32 (37.5%) panic disorder subjects reported a lifetime history of major depression (nine current, three past only). Only two of the 32 (six percent) reported any phobic avoidance. This study confirms the previous findings which suggest that major depression is common in cardiology populations with panic disorder and that phobic avoidance is uncommon in this group.

Panic disorder in cardiology patients.
This paper reviews current evidence from several cardiology populations that suggests panic disorder is prevalent and underdiagnosed. Cardiology patients with atypical angina and no heart disease have a high likelihood of having panic disorder as suggested by studies of two separate cardiology populations. That they resemble psychiatric populations with panic is suggested by their positive response to alprazolam. Although evidence is less clear concerning the relationship between MVP and panic, it appears that patients referred to ECHO and found to have MVP are also likely to have panic. Three other populations deserving further study are patients with 1) pacemaker syndrome, 2) coronary artery disease with atypical angina and 3) certain arrhythmias.

Panic disorder in patients with chest pain and angiographically normal coronary arteries.
Although patients with angiographically normal or near normal coronary arteries are at low risk for cardiac disease, several follow-up studies have shown that many continue to report recurrent chest pain associated with social and work dysfunction. Three diagnostic entities have been proposed to explain the morbidity of this group: microvascular angina, esophageal motility disorders and panic disorder. The purpose of this study was to test the hypothesis that panic disorder is found frequently in patients with chest pain who have normal epicardial vessels. Ninety-four subjects with angiographically normal coronary arteries were interviewed according to a structured psychiatric protocol within 24 hours of their catheterizations. Thirty-two (34%) fit Diagnostic and Statistical Manual of Mental Disorders (third edition, revised) criteria for current panic disorder. Because panic disorder can be effectively treated, physicians should consider this diagnosis in this group of patients. Current research findings suggest that panic disorder, microvascular angina and esophageal disorders may each form the basis for chest pain in approximately 25% of these patients. Miscellaneous problems account for the other 25%.
