Most common complications of Hypertension (5)
- CV disease (stroke)
- CHD, LVH, AF.
- Renal disease: Focal segmental glomerulosclerosis (FSGE)
- HT Retinopathy.
- Peripheral vascular disease (Aortic aneurism/dissection)
Clinical features of Aortic Dissection
- Diastolic murmur if Aortic Regurgitation occurred
- Abrupt chest pain, sharpen,
migrating / irradiating to the
back. - Unequal or absent pulses.
- Difference of BP in arms (more than 20mmHg).
Aortic Dissection Types
- Type A: Ascending aorta.
- Type B: Descending aorta.
Aortic Dissection FIRST Investigation
Transesophageal Echocardiogram
Aortic Dissection BEST Investigation
CT angiogram
Aortic Dissection Treatment
- Beta blockers (to reduce shear stress)
- Immediate Qx for type A
(ascending aorta)
ABI values
> 1.4: Calcification → Refer
1-1.4: Normal
0.9-1: Acceptable
0.8-0.9: Mild Arterial disease → treat risk factors
0.5-0.8: Moderate Arterial disease →
- Treat risk factors
- Refer if signs of gangrene or pain on rest.
< 0.5: Severe → Refer
Aortic dissection/aneurysm vs myocardial infarction investigation
Check if patient stable
if stable:
Initial: ECG
Best: CT angio
If unstable: fast US
Cardiac Tamponade classic quartet
- Hypotension
- Increased JVP
- Tachycardia
- Pulsus paradoxus ( ↓ BP after inhalation)
Beck’s triad
- Hypotension
- Increased JVP
- Muffled heart sounds
Main cause of dysphagia
achalasia
most common oesophageal disorder
achalasia
Dysphagia to solids and liquids + Heartburn unresponsive to PPI + Retained food in the oesophagus on upper endoscopy + Unusually increased esophagogastric junction sphincter tone + failure of muscle relaxation + weight loss + regurgitation getting worse at night/lying down
Achalasia
Achalasia diagnostic feature
Dysphagia for both solids and liquids
Achalasia initial investigation
Plain X -ray
- air fluid levels to see absence of gastric bubble
Barium swallow
- Birds beak/rat tail appearance
OGD endoscopy
- exclude other causes of dysphagia
Achalasia best investigation
oesophageal manometry
- increased tension in lower end of oesophagus
Achalasia complications
- strictures
- oesophageal cancer
Achalasia management
Mild symptoms
- CCB (Nifedipine)
- nitrates
Young px
- Endoscopic Pneumatic dilation of LES
Old px
- Botulinum injection (may need to be repeated every 3 - 12 months) + mild symptoms management
Best
- Laparoscopic Myotomy (Heller’s)
dysphagia + hoarseness + hx of achalasia + thoracic inlet mass
Oesophageal cancer
Progressive dysphagia + Weight loss >10% + Elderly
Rule out Oesophageal cancer
Oesophageal cancer features
▪ Dysphagia progressive continuous - first solids then liquids → odynophagia
▪ Striking unintentional weight loss ( >10%)
▪ Hiccoughs (early sign – phrenic nerve irritation)
▪ Hoarseness and cough (upper 1/3 cancer – recurrent
laryngeal nerve irritation – vocal cord palsy)
▪ Progressive chest discomfort or pain in locally invasive cancer
Oesophageal cancer types
▪ SCC (most common)
▪ Adenocarcinoma
Oesophageal cancer risk factors
SCC:
▪ Smoking & OH → Triple S
(smoking - spirits – SCC)
Adeno:
▪ Barrett’s oesophagus & smoking
Oesophageal cancer investigation
1st test: Barium swallow to locate lesion
▪ Narrowing of oesophagus
▪ Irregular oesophageal borders
▪ apple core appearance
THEN
Endoscopy w/biopsies
Oesophagogastroduodenoscopy
