Among the underlying causes of recurrent pericarditis which require specific treatment strategies (1) mention must also be made of recurrent pericarditis attributable to coeliac disease(2)(3), and recurrent pericarditis attributable either to Type 2 autoimmune endocrinopathy(4) or to hypoadrenalism(5).
Faizallah et al reported 3 patients aged 40, 40, and 56, respectively, with recurrent pericarditis attributable to coeliac disease. The first patient presented with a temperature of 38.5 degrees Celsius, pericardial friction rub, and macrocytic anaemia attributable to folate deficiency. Pericardiocentesis yielded blood stained fluid that tested negative on bacteriological and M tuberculosis culture. Viral studies were negative and there were no malignant cells in the pericardial fluid. He responded well to reducing doses of corticosteroid therapy. However, it was only after a relapse of pericarditis that he had a duodenal biopsy, the latter an evaluation which revealed histological stigmata of coeliac disease. He was subsequently managed with a gluten-free diet(GFD), concurrently with an attempt to taper off the corticosteroid treatment. In spite of two subsequent relapses, corticosteroid treatment was eventually permanently terminated without any further relapse of pericarditis. The second patient was on GFD as well as a small dose of prednisolone at the time of publication of the report. The third patient, characterised by two episodes of pericarditi...

The third patient, characterised by two episodes of pericarditis, was successfully managed solely on a GFD, and had remained free of relapses thereafter(2).
Recurrent pericarditis was also reported by Laine and Holt in a 63 year old patient with coeliac disease(3). That patient experienced two episodes of pericarditis, each characterised by pleuritic pain in association with a pericardial friction rub(4).
Recurrent pericarditis is also a feature of autoimmune endocrinopathy. Examples of this phenomenon were documented in patients with primary hypoadrenalism as well as in patients with primary hypothyroidism(4). Hypoadrenalism-related pericarditis may also be associated with life-threatening cardiac cardiac tamponade(5). In the latter report the patient was a 44 year old woman with unequivocal hypoadrenalism(5). The only uncertainty was whether hypoadrenalism primary or secondary(5). Accordingly, at the very least, the work-up of recurrent pericarditis should include evaluation for coeliac disease and evaluation for endocrinopathy.

The clinical presentation which simulates ST-segment elevation myocardial infarction(STEMI)(1) is one of the most deceptive manifestations of dissecting aortic aneurysm(DAA), deserving detailed analysis notwithstanding its infrequent(2)(3)(4) occurrence.

Conversely, Kosuge et al documented a 4%(9 patients) prevalence of ST segment elevation among 233 subjects with confirmed DAA(3). In Hirata et al ST segment elevation was prevalent in 8.2% of 159 subjects with type A aortic dissection(4). When ST segment elevation occurs as a manifestation of DAA, there is a high prevalence of involvement of the inferior leads, exemplified by 6 of the 9 patients in Kosuge et al(3)., and seven of the 13 cases in Hirata et al(4)., arguably because type A aortic dissection is more likely to compromise the ostium of the right coronary artery than the ostium of the left coronary artery(5).

For example, a literature search of STEMI-like DAA over the period 2000-February 2020 disclosed 4 patients(5)(6)(7)(8) in whom ST segment elevation in the inferior leads was associated with a clinical presentation which included back pain(with concurrent chest pain), and a clinically detectable murmur of aortic regurgitation, all three stigmata, namely, inferior lead ST segment elevation, back pain, and an aortic regurgitant murmur, deserving to be recognised as "red flags" for DAA in a patient with a clinical presentation which includes electrocardiographic ST segment elevation. None of these 4 patients described the back pain as being "tearing" in character. On the basis of that omission the clinicians who managed those patients initially attributed both the associated chest pain and the ST segment elevation solely to acute myocardial infarction(AMI)(5)(6)(7)(8).
The occurrence of focal neurological signs in a patient with ST segment elevation should also be recognised as a "red flag" for DAA. Over the period 2000-2020 a literature search of STEMI-like DAA disclosed 5 patients in whom inferior ST segment elevation occurred in conjunction with focal neurological symptoms comprising hemiparesis(9), right upper limb pain(10), left arm numbness(11), flaccid paraparesis(12), and paraparesis(13), respectively. One of these patients had nonspecific back pain as well(13).
In conclusion, the occurrence of ST segment elevation in one or more of the inferior leads II,III,AVF(with or without concurrent ST segment elevation in other leads) should raise the index of suspicion for DAA(3)(4), especially when such an occurrence is associated with back pain of any description, and/or clinically detectable aortic regurgitation.

Several concerns regarding to methodology of their study should be explained. Authors decided to perform only one measurement of troponin level at 6 hours after end of exercise. In our opinion, sampling after 6, 12, 18 and 24 hours after exercise provide more adequate profile of troponin level and allow to monitor possible post-exercise ischemia.

In another study [3], among HCM patients monitored by HOLTER ECG during normal daily physical activity, maximum heart rate was higher in the troponin positive as compared to troponin negative group (139±9 vs. 125±8 [bpm], p<0.05). Similar association was observed in current exercise study [1]. However, peak exercise left ventricular outflow tract gradient (LVOTG ) was not evaluated [1] despite previously reported association with elevated troponin level [4].
To provide more individualised and comprehensive recommendations with regard to exercise intensity in HCM some additional study should be performed with improved methodology including described above criteria.

In the setting of takotsubo cardiomyopathy (TTC), coronary microvascular dysfunction has been mostly considered as a causative factor (1,2). In their recently published article (1), Montone RA et al have demonstrated, for the first time, the prognostic value of coronary slow flow (CSF) phenomenon in TTC patients. Of note, as we previously discussed, on a theoretical basis, the particular prognostic value of CSF phenomenon in these patients (3), we feel now pleased to notice that this theory has been fully confirmed by a well-designed study (1). Nevertheless, we would like to make a few comments on this issue:
Firstly; temporal emergence of CSF phenomenon might possibly matter in TTC as well. Accordingly; an acutely evolving CSF pattern (due to severe adrenergic discharge (1)) as compared with a sole pre-existing one (emerging long before the index TTC as part of generalized...

Of note, as we previously discussed, on a theoretical basis, the particular prognostic value of CSF phenomenon in these patients (3), we feel now pleased to notice that this theory has been fully confirmed by a well-designed study (1). Nevertheless, we would like to make a few comments on this issue:
Firstly; temporal emergence of CSF phenomenon might possibly matter in TTC as well. Accordingly; an acutely evolving CSF pattern (due to severe adrenergic discharge (1)) as compared with a sole pre-existing one (emerging long before the index TTC as part of generalized endothelial dysfunction) might have stronger cardiovascular prognostic implications in the acute course of TTC (3). In contrast, a pre-existing CSF pattern might be associated with a poor long-term prognosis largely driven by the underlying systemic condition. In this context, CSF pattern in the settings of malignancy and neurological disease might have possibly risen as a pre-existing phenomenon in the present study (1).
Secondly; it seems quite challenging to identify whether a CSF pattern in TTC patients appears to be an acute or pre-existing phenomenon (or both) based on a single coronary angiogram (CAG) (unless making a comparison with previous CAG data). However, a sole pre-existing CSF pattern might be relatively mild and diffuse in nature as compared with a sole or superimposed acute CSF in these patients. Accordingly, did the extent and severity of CSF patterns significantly differ between those with acute cardiac complications (mostly arising due to an acute CSF) and those with exclusively long-term events on follow-up (mostly due to the systemic condition (1) associated with pre-existing CSF) ? In particular, potential prediction of an acute or exclusively pre-existing CSF pattern based on angiographic features might help establish further clinical strategies to improve prognosis (for instance; close supervision for expected acute complications or further diagnostic tests (1) for an obscure malignancy, etc.).
Lastly; vasodilator strategies in TTC patients with a CSF pattern (particularly with a predominant acute component) might be of significant benefit (4). Moreover, given the potential association of future TTC recurrences with excessive adrenergic discharge during the index event (2), TTC patients likely to have an acute CSF pattern might need well-known radical measures including sympathetic ganglion blockade, etc for TTC prevention. Accordingly, we wonder their acute and long-term management strategies in TTC patients with a CSF pattern (1).
In summary, CSF pattern might be considered as a prognostic rather than a causative factor in TTC patients (1,3). However, further categories of this phenomenon (acute vs pre-existing) along with their specific implications in these patients still remain to be established.

I read with interest the super article by Chris Steadman regarding being a clinical director in the NHS. I would add to this article that a particular problem has now become grossly apparent with taking on such a role which is the amount of pension tax that many will find they have to pay in taking such a role on. Previously, leadership and management roles have often attracted a rise in pensionable salary, which was a clear incentive to take them - as per the article, they clearly result in alot of work to the individual and so should be rewarded for this. However with the pension taper which started in 2016 and a low annual allowance, this creates a major problem, with many stories of doctors taking on such roles and receiving a large tax bill as result. How big a bill this may or may not be will depend on the personal circumstances of the individual and the amount of extra pensionable salary the individual trust is offering. For example, under current rules, a £10,000 increase in pensionable pay would result in me doing such a job at a big financial loss in my first year of doing it! Unless the UK government change the pension tax rules, it has created major disincentive for doctors to take on such roles.

Left ventricular apical aneurysm (LVAA) formation in the setting of hypertrophic cardiomyopathy (HCM) usually appears to be associated with a significant mid-ventricular obstruction, and is potentially associated with adverse cardiovascular events (1). In their recently published article (1), Ramchand J et al have suggested LVAA as a major risk marker in this setting.

In their recently published article (1), Ramchand J et al have suggested LVAA as a major risk marker in this setting. Though we fully agree with the authors on this point, we would like to draw attention to certain other conditions including transient LV apical ballooning that might strongly mimick LVAA leading to a potential misdiagnosis in patients with HCM:
Takotsubo cardiomyopathy (TTC) presenting with a transient apical ballooning pattern has been recently suggested to have a pure mechanical basis in certain patients with pre-existing structural heart disease including hypertensive heart disease and HCM largely attributable to acute increments in intraventricular pressure gradient leading to substantially elavated apical wall stress in these patients (2,3). Interestingly, TTC in this setting might have no preceding overt stressors (emotional, etc.) (3), and might be clinically silent generally with vague symptoms and signs along with a relatively delayed recovery pattern (hence; might potentially arise as a sole incidental finding on cardiac imaging). Nevertheless, there might still exist certain imaging clues to differentiate between true LVAA and transient apical ballooning in the setting of HCM:
Firstly; pronounced wall thinning is mostly present in true LVAA (excluding cases with severe apical hypertrophy at baseline) as opposed to transient apical ballooning that generally presents with normal or increased wall thickness.
Secondly; LVAA generally emerges due to a chronic and significant mid-ventricular gradient (1) leading to progressive structural remodeling in the apex. However, mid-ventricular gradient is relatively mild in the setting of apical ballooning that might have been induced by an abrupt, yet; transient elevation of this mild gradient to excessive levels leading to stunning in apical segments (2,3) usually without any preconditioning to such pressure elevations.
And lastly; late gadolinium enhancement (LGE) on MRI is an expected finding in LVAA (1) while it is relatively rare (and with a low-intensity pattern) in TTC (4) presenting with an apical ballooning pattern.
In summary; transient apical ballooning should also be taken into consideration in HCM patients suggestive of having a LVAA pattern on initial imaging. Therefore, a single echocardiographic examination might not suffice for decision-making for primary implantable cardiac defibrillator (ICD) therapy suggesting detailed and serial examinations along with MRI for absolute confirmation of an irreversible true LVAA in these patients.

As a physician dealing with patients with confirmed or suspected Fabry disease, I've read with great interest this editorial. This is a very thought-provoking article, which introduces the process of reclassification of a prevalent variant in the GLA gene associated with the cardiac variant of Fabry disease. I would like to make only a minor correction regarding the nomenclature of the variant mentioned. As written in the article of Valtola et al, the referred variant is c.427G> A and not c.472G> A¹ (transcript NM_000169.2).

Among the underlying causes of recurrent pericarditis which require specific treatment strategies (1) mention must also be made of recurrent pericarditis attributable to coeliac disease(2)(3), and recurrent pericarditis attributable either to Type 2 autoimmune endocrinopathy(4) or to hypoadrenalism(5).
Show MoreFaizallah et al reported 3 patients aged 40, 40, and 56, respectively, with recurrent pericarditis attributable to coeliac disease. The first patient presented with a temperature of 38.5 degrees Celsius, pericardial friction rub, and macrocytic anaemia attributable to folate deficiency. Pericardiocentesis yielded blood stained fluid that tested negative on bacteriological and M tuberculosis culture. Viral studies were negative and there were no malignant cells in the pericardial fluid. He responded well to reducing doses of corticosteroid therapy. However, it was only after a relapse of pericarditis that he had a duodenal biopsy, the latter an evaluation which revealed histological stigmata of coeliac disease. He was subsequently managed with a gluten-free diet(GFD), concurrently with an attempt to taper off the corticosteroid treatment. In spite of two subsequent relapses, corticosteroid treatment was eventually permanently terminated without any further relapse of pericarditis. The second patient was on GFD as well as a small dose of prednisolone at the time of publication of the report. The third patient, characterised by two episodes of pericarditi...
The clinical presentation which simulates ST-segment elevation myocardial infarction(STEMI)(1) is one of the most deceptive manifestations of dissecting aortic aneurysm(DAA), deserving detailed analysis notwithstanding its infrequent(2)(3)(4) occurrence.

Recently Cramer et al. demonstrated very important observation on troponin level increase after exercise in patients with hypertrophic cardiomyopathy (HCM) [1]. Several concerns regarding to methodology of their study should be explained. Authors decided to perform only one measurement of troponin level at 6 hours after end of exercise. In our opinion, sampling after 6, 12, 18 and 24 hours after exercise provide more adequate profile of troponin level and allow to monitor possible post-exercise ischemia. Furthermore, data on prevalence of silent myocardial ischemia (only troponin increase) should be provided. In our study [2] painless ischemia detected by troponin measurement after normal daily physical activity was present in 25% of HCM patients. In another study [3], among HCM patients monitored by HOLTER ECG during normal daily physical activity, maximum heart rate was higher in th...

In the setting of takotsubo cardiomyopathy (TTC), coronary microvascular dysfunction has been mostly considered as a causative factor (1,2). In their recently published article (1), Montone RA et al have demonstrated, for the first time, the prognostic value of coronary slow flow (CSF) phenomenon in TTC patients. Of note, as we previously discussed, on a theoretical basis, the particular prognostic value of CSF phenomenon in these patients (3), we feel now pleased to notice that this theory has been fully confirmed by a well-designed study (1). Nevertheless, we would like to make a few comments on this issue:
Show MoreFirstly; temporal emergence of CSF phenomenon might possibly matter in TTC as well. Accordingly; an acutely evolving CSF pattern (due to severe adrenergic discharge (1)) as compared with a sole pre-existing one (emerging long before the index TTC as part of generalized...
I read with interest the super article by Chris Steadman regarding being a clinical director in the NHS. I would add to this article that a particular problem has now become grossly apparent with taking on such a role which is the amount of pension tax that many will find they have to pay in taking such a role on. Previously, leadership and management roles have often attracted a rise in pensionable salary, which was a clear incentive to take them - as per the article, they clearly result in alot of work to the individual and so should be rewarded for this. However with the pension taper which started in 2016 and a low annual allowance, this creates a major problem, with many stories of doctors taking on such roles and receiving a large tax bill as result. How big a bill this may or may not be will depend on the personal circumstances of the individual and the amount of extra pensionable salary the individual trust is offering. For example, under current rules, a £10,000 increase in pensionable pay would result in me doing such a job at a big financial loss in my first year of doing it! Unless the UK government change the pension tax rules, it has created major disincentive for doctors to take on such roles.

Left ventricular apical aneurysm (LVAA) formation in the setting of hypertrophic cardiomyopathy (HCM) usually appears to be associated with a significant mid-ventricular obstruction, and is potentially associated with adverse cardiovascular events (1). In their recently published article (1), Ramchand J et al have suggested LVAA as a major risk marker in this setting. Though we fully agree with the authors on this point, we would like to draw attention to certain other conditions including transient LV apical ballooning that might strongly mimick LVAA leading to a potential misdiagnosis in patients with HCM:
Show MoreTakotsubo cardiomyopathy (TTC) presenting with a transient apical ballooning pattern has been recently suggested to have a pure mechanical basis in certain patients with pre-existing structural heart diseas...
As a physician dealing with patients with confirmed or suspected Fabry disease, I've read with great interest this editorial. This is a very thought-provoking article, which introduces the process of reclassification of a prevalent variant in the GLA gene associated with the cardiac variant of Fabry disease. I would like to make only a minor correction regarding the nomenclature of the variant mentioned. As written in the article of Valtola et al, the referred variant is c.427G> A and not c.472G> A¹ (transcript NM_000169.2).
