Management of Hypertrophic Obstructive Cardiomyopathy with Concurrent Hypertension and Intracerebral Haemorrhage: A Case Report
Open accessAbstract
Hypertrophic Obstructive Cardiomyopathy (HOCM) is primarily a hereditary genetic disorder that presents difficulties in managing hypertension using a wide range of antihypertensive medications. It is crucial to steer clear of any substance that reduces preload or afterload in this situation, making beta-adrenergic receptor antagonists the ideal option. Hereby is a case of a 41-year-old who reported to the Medicine Outpatient Department (OPD) with complaints of weakness in the right upper and lower limbs for two days and altered sensorium. The patient was recently diagnosed with hypertension, and a Computed Tomography (CT) scan showed a left gangliocapsular bleed with a 3 mm midline shift. Echocardiography revealed HOCM. The patient was started on antioedema drugs and metoprolol. A repeat CT scan showed a decrease in the size of the bleed and surrounding oedema. The patient’s consciousness improved, and blood pressure came under control. He was discharged with antihypertensives for regular follow-ups. Overall, this case underscores the complex interplay between HOCM and hypertension, the challenges in managing hypertension in HOCM patients, and the critical role of beta-adrenergic receptor antagonists in this setting. It highlights the need for a tailored approach to hypertension management and the importance of early recognition and appropriate intervention in patients with HOCM presenting with complications such as intracranial haemorrhage.

TL;DR
A single case report describes a 41-year-old man with newly detected hypertension who presented with right-sided weakness and altered sensorium, found to have a left gangliocapsular intracerebral haemorrhage alongside echocardiographically diagnosed hypertrophic obstructive cardiomyopathy (HOCM). He was managed with mannitol, levetiracetam, and metoprolol, with radiological and clinical improvement, illustrating the difficulty of treating hypertension when preload- and afterload-reducing drugs are contraindicated.
Key findings
- On presentation: pulse 74 beats per minute, blood pressure 180/100 mmHg, Glasgow Coma Score E2V2M4, 0/5 power in the right upper and lower limbs with exaggerated right-sided reflexes, and fundus examination showing early papilloedema.
- CT brain showed a well-defined hyperdense area (HU: 60–68) measuring approximately 36×50×27 mm (CC×AP×TR) in the left gangliocapsular region, thalamus, and corona radiata, with perilesional oedema, sulcal/Sylvian fissure/left lateral ventricle effacement, and a 3 mm midline shift to the right.
- Echocardiography revealed moderate concentric left ventricular hypertrophy with HOCM; ECG showed sinus tachycardia, an LVH pattern, and deep Q-wave and T-wave inversions in all leads.
- After treatment with injections of mannitol, levetiracetam, and metoprolol, a repeat CT showed the bleed decreased to 21×18×20 mm (CC×AP×TR) with reduced surrounding oedema; consciousness and right-sided limb power improved over two weeks, and the patient was discharged on antihypertensives for follow-up.
- The discussion cites literature that hypertension is found in 30 to 50% of patients with HOCM, that HOCM prevalence ranges from 0.02 to 0.2% in Western and Asian countries, and that ACE inhibitors and nitrates should be avoided because they worsen LVOT obstruction by reducing afterload.
Methods
- Design: single case report from the Department of Internal Medicine, Dr. D. Y. Patil Medical College, Hospital and Research Centre, Pune, Maharashtra, India.
- Data: clinical history and examination, routine blood investigations, ECG, CT brain (initial and repeat), and echocardiography in one 41-year-old male patient.
- Analysis: descriptive narrative of the clinical course, with the discussion contextualising the case against cited literature on HOCM and concurrent hypertension; no formal statistical analysis was performed.
Limitations
- The paper states no explicit limitations section.
- Evident from the text: this is a single case report with no control or comparison group, so no causal or generalisable conclusions can be drawn; the follow-up described is short (two weeks, with the patient "now on regular follow-up").
- Evident from the text: the discussion cites Wang Z et al. as describing a right-sided gangliocapsular bleed in patients with HOCM, whereas the index patient's bleed was left-sided, an inconsistency in the paper's own framing.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
